Fabspeed Exhaust
- Porsche 997 MKII GT2 RS 2011-13
The Fabspeed 70mm Supersport X-Pipe Exhaust System is a high-performance exhaust upgrade designed specifically for the 2011 Porsche 997.2 GT2 RS.
Fits:
- Porsche 997 MKII GT2 RS 2011-13
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 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.
