- Porsche 911 1975-1977 3.0L Turbo (930)
- Porsche 911 1978-1989 3.3L Turbo (930)
The Fabspeed Sport Muffler Bypass Exhaust System with Catalyst is a performance-focused exhaust upgrade designed for the 1976–1989 Porsche 911 Turbo / 930.
Fits:
- Porsche 911 1976-1977 3.0L Turbo (930)
- Porsche 911 1978-1989 3.3L Turbo (930)
The system replaces the heavier and more restrictive factory muffler arrangement with a freer-flowing single-outlet muffler bypass system incorporating a high-flow HJS Sport Catalytic Converter.
Constructed from 14–16 gauge T304 stainless steel, the system uses large 3.0-inch / 76.5mm CNC mandrel-bent tubing to provide a smoother, less restrictive route for exhaust gases leaving the turbocharger.
A Deluxe Oval Style Tip in polished chrome is included, providing a distinctive finished appearance at the rear of the vehicle.
Fabspeed states that the system is designed to improve horsepower and torque while reducing weight compared with the bulky factory muffler system. Specific horsepower, torque and weight figures are currently listed by Fabspeed as TBD.
What This Product Does:
The exhaust system carries combustion gases away from the engine and turbocharger while controlling exhaust noise, flow and emissions.
On the Porsche 930's turbocharged engine, exhaust gases leaving the turbine must pass through the catalytic converter, muffler and associated pipework before exiting the vehicle.
The Fabspeed system replaces the conventional rear muffler with a more direct bypass arrangement, helping reduce restriction downstream of the turbocharger.
Its main functions and benefits include:
- Improving exhaust gas flow
- Reducing post-turbo exhaust restriction
- Eliminating the bulky factory muffler
- Supporting improved throttle response
- Supporting increased horsepower and torque
- Reducing rear exhaust-system weight
- Producing a louder and more aggressive turbocharged exhaust note
- Providing a high-flow catalytic converter
- Replacing ageing factory exhaust components
- Improving corrosion resistance through stainless-steel construction
Because the muffler is bypassed, the system provides a considerably more direct and performance-focused exhaust character than the standard arrangement.
Symptoms Of Wear Or Failure:
The original exhaust components on a Porsche 930 may now be several decades old. Repeated heating and cooling cycles, condensation, vibration and corrosion can gradually deteriorate mufflers, catalytic converters and pipework.
Common symptoms include:
- Rust or corrosion on the exhaust system
- Cracks around pipes, seams or welds
- Exhaust blowing or hissing noises
- Black soot around leaking connections
- Loose or damaged exhaust clamps
- Rattling from the muffler
- Metallic rattling from the catalytic converter
- Excessively loud or irregular exhaust noise
- Exhaust fumes around the rear of the vehicle
- Damaged or weakened mounting points
- Reduced throttle response
- Reduced engine performance
- Increased turbo lag
- Excessive exhaust restriction
- Sulphur-like or unusual exhaust smells
- Visible damage or deformation of exhaust components
Internal muffler components can also deteriorate and become loose, producing rattling or obstructing exhaust flow.
Why Replacement Matters:
A damaged or restrictive exhaust system can affect both performance and reliability.
Leaks can allow hot exhaust gases to escape before reaching the intended outlet. This may expose surrounding engine or body components to unnecessary heat and create excessive noise.
Corrosion can also weaken pipework and mounting points until sections of the exhaust become loose or fail.
A damaged catalytic converter can be particularly restrictive if the internal substrate begins to break down or collapse.
On a turbocharged Porsche 930, excessive restriction downstream of the turbocharger can work against efficient exhaust evacuation. This may contribute to:
- Slower turbo response
- Reduced throttle response
- Loss of engine performance
- Increased exhaust temperatures
Replacing deteriorated exhaust components restores a secure and unobstructed exhaust path.
For vehicles with a serviceable standard exhaust, fitting the Fabspeed system provides the additional benefits of reduced restriction, lower weight and a considerably more aggressive exhaust sound.
NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.
For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.
If you are located outside the UK, please check your local laws and regulations to ensure compliance.

- Porsche 997 MK1 GT3 / GT3 RS 2007-09
The Fabspeed Sport Headers are a high-performance replacement for the factory exhaust manifolds and catalytic converter assemblies on the 2006–2009 Porsche 997 GT3 and GT3 RS.
Fits:
- Porsche 997 MK1 GT3 / GT3 RS 2006-09
Designed to improve exhaust flow throughout the engine's operating range, these headers use high-velocity 3-into-1 merge collectors to combine exhaust gases efficiently before they pass through the supplied 200-cell HJS Sport Catalytic Converters.
The system is manufactured from high-quality 14–16 gauge CNC mandrel-bent stainless steel, providing excellent resistance to heat, corrosion and repeated thermal cycling.
Fabspeed reports gains of approximately 22 horsepower and 37 lb-ft of torque, together with a 2 lb reduction in weight compared with the factory arrangement. Actual results will vary depending on vehicle condition, specification and operating conditions.
What This Product Does:
The exhaust headers collect combustion gases leaving the engine cylinders and direct them into the remainder of the exhaust system.
Efficient header design is particularly important on the naturally aspirated GT3 engine because exhaust pulse timing and scavenging influence how effectively the cylinders can clear spent gases and draw in the next intake charge.
The Fabspeed Sport Headers are designed to:
- Improve exhaust gas flow
- Reduce restriction compared with the factory header and catalyst arrangement
- Improve exhaust scavenging
- Increase throttle response
- Support increased horsepower and torque
- Produce a stronger sports-car exhaust note
- Provide high-flow catalytic converter performance
- Replace ageing or damaged factory exhaust manifolds
- Reduce a small amount of rear exhaust weight
The 3-into-1 pyramidal merge collectors are designed to combine the exhaust pulses from each cylinder bank smoothly, helping maintain gas velocity and reduce turbulence.
Symptoms Of Wear Or Failure:
The original headers and catalytic converters operate under extreme temperatures and experience repeated expansion and contraction throughout their service life.
Common signs of deterioration include:
- Ticking or tapping noises during cold starts
- Blowing or hissing sounds from the exhaust manifold area
- Black soot around leaking header joints
- Cracks in the manifold or welds
- Warped mounting flanges
- Broken or corroded mounting hardware
- Exhaust fumes around the engine or rear of the vehicle
- Increased exhaust noise
- Reduced throttle response
- Noticeable loss of engine performance
- Check Engine Light relating to catalyst efficiency
- Metallic rattling from inside a catalytic converter
- Sulphur-like or unusual exhaust smells
- Increased exhaust restriction
- Loss of power at higher engine speeds
- Excessive heat around the catalyst area
A catalytic converter can also deteriorate internally. The substrate may crack, melt or break apart, potentially restricting the exhaust path.
Why Replacement Matters:
A damaged or leaking exhaust header reduces the efficiency of the exhaust system and can allow extremely hot gases to escape into surrounding areas.
Cracks or leaking flanges can cause:
- Unwanted exhaust noise
- Reduced exhaust scavenging
- Heat exposure to surrounding components
- Loss of engine response
- Further deterioration of exhaust joints and hardware
A deteriorating catalytic converter can be equally problematic.
If the catalyst substrate becomes damaged or partially blocked, exhaust gases cannot leave the engine efficiently. Increased backpressure can reduce performance and place additional thermal stress on the exhaust system.
Replacing deteriorated headers and catalysts helps restore:
- A secure and leak-free exhaust path
- Efficient exhaust scavenging
- Correct exhaust gas flow
- Consistent throttle response
- Proper catalyst function
- Reduced exhaust restriction
- Reliable long-term exhaust operation
For vehicles with healthy factory components, upgrading to the Fabspeed system provides the additional benefit of freer-flowing headers and sport catalysts designed to improve overall engine response.

- Porsche 996 GT2 2001-05
The Fabspeed X-50 Style Exhaust Tips are premium replacement exhaust outlets designed for the 2001–2005 Porsche 996 GT2.
Fits:
- Porsche 996 GT2 2001-05
Designed as a direct bolt-on upgrade, these tips can be fitted to the factory exhaust system as well as compatible aftermarket exhausts. The X-50-inspired design gives the rear of the 996 GT2 a distinctive performance-focused appearance while providing a durable replacement for ageing, damaged or heavily discoloured original exhaust outlets.
Manufactured from high-quality 14–16 gauge T304L stainless steel, the tips are engineered to withstand high exhaust temperatures, condensation, road contamination and repeated thermal cycles.
What This Product Does:
Exhaust tips form the visible final section of the exhaust system and provide the outlet through which exhaust gases leave the vehicle.
The Fabspeed X-50 Style Tips are designed primarily to:
- Replace worn, corroded or damaged original exhaust tips
- Provide an X-50-inspired performance appearance
- Maintain secure and correctly positioned exhaust outlets
- Refresh the appearance of the rear exhaust system
- Fit factory and compatible aftermarket exhaust systems
- Provide durable stainless-steel construction
- Allow a straightforward bolt-on upgrade without replacing the complete exhaust
These tips are primarily an appearance, durability and replacement upgrade rather than a significant engine-performance modification.
Symptoms Of Wear Or Failure:
Exhaust tips are continuously exposed to high temperatures, moisture, condensation, exhaust deposits and road debris.
Common signs that replacement may be required include:
- Surface rust or corrosion
- Pitting in the metal
- Permanent staining or heat discolouration
- Heavy soot accumulation
- Peeling or deterioration of the original finish
- Dents or deformation
- Scratches or impact damage
- Loose mounting points
- Rattling or vibration
- Cracks around welds or attachment areas
- Tips sitting unevenly or out of alignment
- Contact with the bumper or surrounding trim
- Severely corroded mounting hardware
- A deteriorated appearance that cannot be restored through cleaning or polishing
Cosmetic deterioration alone may not affect exhaust operation, but severe corrosion or damaged mounting points can eventually allow the tip to become loose.
Why Replacement Matters:
Exhaust tips are a prominent feature at the rear of the Porsche 996 GT2, so worn or damaged outlets can noticeably affect the appearance of the vehicle.
More importantly, a loose or distorted exhaust tip can vibrate, rattle or move sufficiently to contact the rear bumper or surrounding trim.
Continued movement can result in:
- Unwanted rattling and vibration
- Damage to surrounding bumper trim
- Increased stress on exhaust mounting hardware
- Poor exhaust outlet alignment
- Further deterioration of attachment points
- Possible detachment if mounting areas become severely weakened
Replacing worn exhaust tips helps restore secure mounting, correct positioning and a clean finished appearance.
Where the main exhaust system remains serviceable, replacing only the tips is also a practical way to refresh the vehicle without replacing silencers, catalytic converters or other major exhaust components.

- Porsche 997 MKII GT2 RS 2011-13
The Fabspeed HJS German Sport Catalytic Converters are high-flow replacement catalysts designed specifically for the 2011 Porsche 997.2 GT2 RS.
Fits:
- Porsche 997 MKII GT2 RS 2011-13
Using premium 200-cell HJS HD Sport catalytic converters, the system is engineered to reduce exhaust restriction compared with the original catalysts while continuing to provide catalytic emissions treatment.
The catalysts are integrated into high-quality 14–16 gauge CNC mandrel-bent T304 stainless-steel pipework, providing excellent resistance to exhaust heat, corrosion and repeated thermal cycling.
Designed as a direct replacement for the factory catalytic converters, this upgrade is intended to improve exhaust flow, throttle response and exhaust character without converting the vehicle to a catalyst-delete configuration.
What This Product Does:
Catalytic converters form part of the vehicle's emissions-control and exhaust system.
Their primary purpose is to chemically convert harmful exhaust pollutants into less harmful gases before they leave the tailpipes. However, exhaust gases must also pass through the catalyst substrate, meaning its design can influence exhaust restriction.
The Fabspeed HJS Sport Catalytic Converters are designed to:
- Reduce exhaust restriction compared with more restrictive catalysts
- Improve exhaust gas flow
- Support improved throttle response
- Allow the turbochargers to evacuate exhaust gases more efficiently
- Provide catalytic emissions treatment
- Produce a stronger performance exhaust note
- Maintain a catted exhaust configuration
- Replace ageing, damaged or restricted original catalytic converters
- Provide durable stainless-steel construction
Fabspeed states that the 200-cell HJS EMITEC catalysts can flow up to approximately 90–93% of a straight pipe in many applications, while retaining catalytic functionality.
Symptoms Of Wear Or Failure:
Catalytic converters operate at extremely high temperatures and can deteriorate through age, contamination, physical damage or repeated thermal stress.
Common symptoms of a failing or restricted catalytic converter include:
- Check Engine Light relating to catalyst efficiency
- Reduced engine performance
- Sluggish throttle response
- Increased turbo lag
- Loss of power at higher engine speeds
- Excessive exhaust backpressure
- Metallic rattling from inside the catalyst
- Broken or loose catalyst substrate
- Sulphur or rotten-egg-like exhaust smell
- Unusually high exhaust temperatures
- Increased fuel consumption
- Failed emissions testing
- Irregular or restricted exhaust flow
- Excessive heat around the catalytic converter area
- Visible damage or cracking around the catalyst housing
- Black soot around leaking exhaust connections
A damaged catalyst substrate can break apart internally and partially obstruct the exhaust path, significantly increasing restriction.
Why Replacement Matters:
A deteriorated catalytic converter can affect both emissions performance and engine operation.
If the internal catalyst substrate begins to collapse or become blocked, exhaust gases cannot leave the engine as efficiently. On a turbocharged engine such as the GT2 RS, this increased post-turbo restriction can negatively affect throttle response and turbocharger performance.
Excessive restriction can also increase exhaust temperature and thermal stress within the system.
Replacing damaged or restricted catalytic converters helps restore:
- Proper exhaust gas flow
- Reduced exhaust backpressure
- Consistent turbocharger response
- Correct catalytic emissions treatment
- Normal throttle response
- A secure and leak-free exhaust system
Replacement is also important when the catalyst substrate has physically deteriorated, as loose material can continue to break apart and further obstruct the exhaust.

- Porsche 997 MKII GT2 RS 2011-13
The Fabspeed Sport Headers are a high-performance replacement for the factory exhaust manifolds on the 2011 Porsche 997.2 GT2 RS.
Fits:
- Porsche 997 MKII GT2 RS 2011-13
Designed to improve the flow of exhaust gases from the cylinder heads to the turbochargers, these headers provide a less restrictive exhaust path intended to improve engine response and turbocharger performance.
The system is manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel and incorporates high-velocity 3-into-1 merge collectors. These CAD-designed collectors bring the exhaust gases from each bank together efficiently before they reach the turbochargers, helping improve exhaust scavenging and minimise unnecessary turbulence.
Fabspeed designed the headers as a direct bolt-on replacement for the factory manifolds, making them suitable both as a performance upgrade and as a replacement for damaged or deteriorated original headers.
What This Product Does:
The exhaust headers collect combustion gases leaving the engine's cylinders and direct them towards the turbochargers.
On the twin-turbocharged GT2 RS, exhaust gas energy drives the turbine wheels that generate boost. Efficient exhaust flow before the turbochargers is therefore important for both engine breathing and turbo response.
The Fabspeed Sport Headers are designed to:
- Improve exhaust gas flow
- Reduce restriction before the turbochargers
- Improve exhaust scavenging
- Deliver exhaust gases more efficiently to the turbochargers
- Support faster turbo boost response
- Improve throttle response
- Support increased engine performance
- Replace ageing factory exhaust manifolds
- Provide durable stainless-steel construction
- Maintain smooth internal flow through mandrel-bent tubing
The high-velocity 3-into-1 merge collectors are designed to combine exhaust pulses smoothly and efficiently before the gases enter the turbochargers.
Symptoms Of Wear Or Failure:
Exhaust headers operate in an extremely demanding environment and are continually subjected to high temperatures, vibration and repeated thermal cycling.
Common signs of damaged or deteriorating headers include:
- Ticking or tapping noises, particularly during a cold start
- Blowing or hissing noises from the manifold area
- Black soot deposits around header joints
- Visible cracks in the manifold or welds
- Exhaust leaks around the cylinder-head flanges
- Warped or distorted mounting flanges
- Broken or heavily corroded studs and nuts
- Increased exhaust noise
- Exhaust fumes around the engine compartment
- Reduced throttle response
- Slower or inconsistent turbo response
- Loss of engine performance
- Increased heat around nearby engine components
Similar symptoms can also be caused by failed exhaust gaskets, loose fasteners or leaks elsewhere in the exhaust system, so the complete assembly should be inspected before replacement.
Why Replacement Matters:
A secure and leak-free exhaust route between the cylinder heads and turbochargers is particularly important on a high-performance turbocharged engine.
If a header cracks or develops a leaking flange, exhaust gases can escape before they reach the turbocharger. This reduces the amount of exhaust energy available to drive the turbine and may contribute to slower boost response and reduced performance.
Escaping gases can also expose surrounding components to excessive heat and produce unwanted exhaust noise.
Replacing damaged headers helps restore:
- A sealed exhaust path
- Efficient exhaust delivery to the turbochargers
- Consistent turbocharger response
- Correct exhaust gas flow
- Reduced exhaust leakage
- Improved reliability around the manifold area
For vehicles with serviceable factory headers, upgrading to the Fabspeed system provides a freer-flowing design intended to improve exhaust scavenging, throttle response and turbo boost response.

The system replaces the factory rear mufflers and catalytic converters with a freer-flowing 70mm X-pipe arrangement incorporating 200-cell HJS Sport Catalytic Converters. It is engineered to reduce exhaust restriction, improve throttle response and give the GT2 RS a more pronounced, exotic performance exhaust note.
Manufactured from high-quality 14–16 gauge CNC mandrel-bent T304L stainless steel, the system is designed to withstand the extreme temperatures and operating demands of the twin-turbocharged GT2 RS.
Fabspeed's Deluxe GT2 Style exhaust tips are also included, providing a finished appearance that complements the rear of the vehicle.
What This Product Does:
The exhaust system carries combustion gases away from the turbochargers and engine while controlling exhaust flow, emissions and sound.
On a high-performance turbocharged engine such as the GT2 RS, reducing unnecessary exhaust restriction downstream of the turbochargers can help gases leave the system more efficiently.
The Fabspeed Supersport X-Pipe is designed to:
- Improve exhaust gas flow
- Reduce post-turbo exhaust restriction
- Improve throttle response
- Support more responsive turbocharger operation
- Produce a stronger and more exotic exhaust sound
- Replace the restrictive factory rear mufflers
- Provide high-flow catalytic converter performance
- Improve long-term corrosion resistance
- Provide a durable stainless-steel replacement for ageing factory components
- Enhance the appearance of the exhaust with Deluxe GT2 Style tips
The X-pipe layout also allows exhaust gases from both sides of the engine to interact within the system, contributing to its distinctive sound characteristics.
Symptoms Of Wear Or Failure:
The exhaust system on a high-performance vehicle such as the 997.2 GT2 RS experiences extreme heat, vibration and repeated thermal cycles.
Signs of deterioration can include:
- Exhaust blowing, ticking or hissing noises
- Cracks around pipes, welds or joints
- Black soot around leaking connections
- Loose or damaged exhaust clamps
- Corrosion or surface deterioration
- Metallic rattling from the catalytic converters
- Increased or irregular exhaust noise
- Exhaust fumes around the rear of the vehicle
- Reduced throttle response
- Increased turbo lag
- Loss of engine performance
- Check Engine Light associated with catalyst efficiency
- Unusual sulphur-like exhaust smells
- Damaged or deformed exhaust pipework
- Loose exhaust tips or poor outlet alignment
Catalytic converters can also deteriorate internally through extreme heat and repeated thermal cycling. The catalyst substrate may break apart, become loose or partially block the exhaust path.
Why Replacement Matters:
A damaged or restrictive exhaust system can affect both engine performance and reliability.
Exhaust leaks allow hot gases to escape before reaching the intended outlets. This can increase heat exposure around nearby components, cause unwanted noise and gradually worsen as cracks or joints deteriorate.
A damaged or partially blocked catalytic converter can create additional exhaust backpressure.
On a twin-turbocharged Porsche GT2 RS, excessive restriction downstream of the turbochargers can work against efficient exhaust evacuation and may negatively affect throttle and turbocharger response.
Replacing deteriorated exhaust components helps restore:
- A secure and leak-free exhaust path
- Efficient exhaust gas evacuation
- Consistent turbo response
- Correct catalytic converter operation
- Proper exhaust outlet positioning
- Reduced risk of further heat or corrosion-related damage
For a vehicle with a healthy standard exhaust, upgrading to the Fabspeed system provides the additional advantages of freer exhaust flow, a more aggressive exhaust note and performance-focused construction.

- Porsche 996 GT2 2001-05
The Fabspeed Sport Headers are a high-performance replacement for the factory exhaust manifolds on 2001–2005 Porsche 996 Turbo and 996 GT2 models.
Fits:
- Porsche 996 GT2 2001-05
Designed to improve the flow of exhaust gases from the cylinder heads to the turbochargers, these headers use equal-length primary tubing combined with high-velocity 3-into-1 merge collectors. This arrangement is engineered to improve exhaust flow and pulse-wave scavenging while reducing unnecessary restriction before the turbochargers.
Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the headers provide excellent resistance to corrosion, high exhaust temperatures and repeated thermal cycling.
Fabspeed quotes performance gains of approximately 12 wheel horsepower and 14 ft-lb of torque. Actual results can vary depending on vehicle condition, modifications and operating conditions.
What This Product Does:
The exhaust headers collect combustion gases from the engine's cylinders and direct them towards the turbochargers.
On a turbocharged engine, exhaust energy is used to drive the turbine wheels and generate boost. Maintaining efficient flow between the cylinder heads and turbochargers is therefore important for engine response and overall performance.
The Fabspeed Sport Headers are designed to:
- Improve exhaust gas flow
- Reduce restriction before the turbochargers
- Improve exhaust pulse scavenging
- Provide more efficient delivery of exhaust gases to the turbochargers
- Support improved throttle and engine response
- Support increased horsepower and torque
- Replace ageing factory manifolds
- Provide durable stainless-steel construction
- Maintain consistent pipe diameter through mandrel-bent sections
The equal-length design helps coordinate exhaust pulses from each cylinder, while the 3-into-1 collectors smoothly combine the gases before they enter the turbochargers.
Symptoms Of Wear Or Failure:
Exhaust headers operate under extremely demanding conditions and are continually exposed to high temperatures, vibration and repeated heating and cooling cycles.
Common signs of worn, cracked or leaking headers include:
- Ticking or tapping noises, particularly when the engine is cold
- Blowing or hissing noises from the manifold area
- Black soot deposits around header joints
- Visible cracks in the manifold or welds
- Exhaust leaks around the cylinder-head flanges
- Warped mounting flanges
- Broken or corroded mounting studs and nuts
- Increased exhaust noise
- Exhaust fumes around the engine area
- Reduced throttle response
- Slower or inconsistent turbo response
- Loss of engine performance
- Increased heat around neighbouring engine components
Similar symptoms can also be caused by failed exhaust gaskets or loose mounting hardware, so the complete manifold assembly should be inspected before replacement.
Why Replacement Matters:
A properly sealed exhaust path between the cylinder heads and turbochargers is particularly important on a turbocharged engine.
If a header cracks or develops a leaking flange, some exhaust gas can escape before reaching the turbocharger. This reduces the exhaust energy available to drive the turbine and can contribute to slower turbo response and reduced engine performance.
Escaping exhaust gases can also expose surrounding components to excessive heat and create unwanted noise.
Replacing damaged or deteriorated headers helps restore:
- A secure and leak-free exhaust path
- Efficient exhaust delivery to the turbochargers
- Consistent turbocharger response
- Correct exhaust flow
- Reduced exhaust leakage
- Reliable long-term operation
For vehicles with healthy factory headers, upgrading to the Fabspeed system provides a freer-flowing equal-length design intended to improve scavenging and support increased performance.
