A Quick Look at Fabspeed
Fabspeed information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where Fabspeed is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Typical reasons people replace these parts include upgrading tired or corroded factory exhaust components, tailoring sound and response for fast-road or track use, and supporting wider tuning packages.
- Common symptoms that lead owners to inspect or change related parts include exhaust leaks, rattles, drone, heat-related fatigue, and loss of performance that may also be linked to boost or vacuum issues.
- After installation, it is sensible to refresh mounts and hardware where worn, and to carry out a careful check for leaks once everything has heat-cycled.
- Consider whether supporting ECU mapping or health checks are appropriate for your Porsche, depending on how extensive your hardware changes are.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Engine Tuning — Engine tuning parts and upgrades for Porsche are used to improve drivability, throttle response and power, or to support changes such as intake, exhaust, or forced induction. They are typically chosen once the engine is in good health, as tuning cannot compensate for underlying mechanical faults.
- Before any significant tuning work, check overall engine condition, including compression or leak-down where appropriate, fuel system health, sensor data, and that there are no boost or vacuum leaks.
- Avoid using calibration changes to hide rough running or misfires, as the mechanical root cause still needs to be addressed.
Air Filters — Air filters for Porsche protect the engine from dirt while maintaining the airflow that correct fuelling and performance depend on. Owners often replace or upgrade filters to restore airflow, support tuning work, or improve serviceability while keeping good filtration.
- Service intervals depend on use: dusty environments or frequent track days may justify more frequent inspection and cleaning or replacement.
- If using oiled performance filters, follow the manufacturer’s oiling instructions carefully to avoid contaminating sensitive airflow sensors.
Air Induction Kits — Induction kits for Porsche replace or re-route parts of the intake system to change airflow, response and sound. They are usually part of a wider tuning package and are selected to balance intake temperatures, flow and sensor stability.
- When fitting an induction kit, ensure joints and connections are well sealed to prevent unmetered air entering the engine or causing drivability issues.
- Positioning and heat management are important: shielding from hot engine-bay air helps keep intake temperatures, and therefore performance, more consistent.
Exhausts — Exhaust upgrades for Porsche are commonly chosen to replace corroded or leaking factory systems, refine the car’s sound, reduce weight or improve gas flow as part of a tuning package. The right choice depends on how the car is used and the balance you want between sound, comfort and responsiveness.
- When planning an exhaust change, consider the complete system, including catalytic converters, to keep within your local emissions and noise requirements.
- Replacing aged gaskets, clamps, mounts and rusted fixings at the same time as the exhaust usually improves fitment and reduces the chance of future leaks or rattles.
All Silencers / Mufflers — This category covers a range of Porsche silencer and muffler layouts, from standard-style replacements to sport and valved options. Selection is usually guided by corrosion or damage to existing parts, unwanted noise or drone, or a desire to change the exhaust character while staying within comfort and usage needs.
- To narrow down the correct layout, compare inlet and outlet positions, hanger locations and pipe diameters on your current system against the product details.
- When choosing between standard, sport or switchable systems, think about typical journeys and cabin noise tolerance so you end up with a sound level that suits day-to-day use.

- Porsche 964 (911) TURBO 3.3L 1991-93
- Porsche 964 (911) TURBO 3.6L 1991-93
The Fabspeed Porsche 964 Turbo / 965 / C2 Turbo Secondary Muffler Bypass Pipe is a performance exhaust upgrade designed to replace the factory secondary rear muffler with a freer-flowing stainless-steel pipe.
Fits:
- Porsche 964 (911) TURBO 3.3L 1990-94
- Porsche 964 (911) TURBO 3.6L 1990-94
Designed for both 3.3L and 3.6L Porsche 964 Turbo / 965 models, the bypass pipe reduces restriction in the rear exhaust system while retaining the vehicle's catalytic converter. This provides improved exhaust flow, sharper throttle response, reduced rear-end weight and a more pronounced turbocharged flat-six exhaust note.
Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the pipe is a direct replacement for the original Porsche secondary muffler.
Fabspeed lists 12 HP and 10 lb-ft for this product and states that removing the factory secondary muffler saves approximately 25 lb / 11.4 kg from the rear of the vehicle. Performance figures are manufacturer-reported and actual results will vary according to vehicle specification, condition and testing environment.
What This Product Does:
The secondary muffler is positioned downstream of the catalytic converter and is primarily responsible for reducing exhaust noise before gases exit through the rear exhaust tip.
While effective at controlling sound, the internal chambers and passages of a conventional muffler can also create resistance to exhaust flow.
The Fabspeed Secondary Muffler Bypass Pipe removes this muffler and replaces it with a freer-flowing pipe.
The upgrade is designed to provide:
- Improved exhaust-gas flow
- Reduced rear exhaust restriction
- Improved throttle response
- Increased performance potential
- Reduced rear-end weight
- Stronger turbocharged flat-six exhaust sound
- More pronounced turbo whistle
- More direct exhaust path
Improved Exhaust Flow:
Replacing the factory secondary muffler removes internal chambers and sound-control structures from this section of the exhaust.
The resulting straighter exhaust route is designed to reduce restriction.
Potential benefits include:
- Faster exhaust-gas evacuation
- Reduced backpressure
- Improved turbo exhaust flow
- Sharper throttle response
- Improved performance throughout the RPM range
The exact difference will depend on the condition and specification of the complete engine and exhaust system.
Enhanced Turbocharged Flat-Six Sound:
Removing the secondary muffler allows considerably more of the 964 Turbo's natural exhaust character to be heard.
The result is a deeper and more pronounced turbocharged flat-six sound, accompanied by increased turbo whistle.
Drivers can expect:
- Deeper exhaust tone
- Increased exhaust presence
- Stronger sound under acceleration
- More noticeable turbo whistle
- More pronounced flat-six character
- Sportier overall exhaust note
The final sound will depend on the rest of the exhaust system fitted to the vehicle.
Why Upgrading Matters:
The original secondary muffler does not need to have failed before this component is installed.
This product is primarily a performance, sound and weight-reduction upgrade.
Reasons for upgrading include:
- Removes the restrictive factory secondary muffler
- Improves exhaust flow
- Improves throttle response potential
- Manufacturer-listed 12 HP / 10 lb-ft
- Approx. 25 lb / 11.4 kg rear weight saving
- Stronger turbocharged flat-six sound
- More noticeable turbo whistle
- Retains the catalytic converter
- T304L stainless-steel construction
- CNC mandrel-bent tubing
- Direct replacement for the factory secondary muffler
- Suitable for both 3.3L and 3.6L 964 Turbo applications

- Porsche 970.2 Panamera V6 3.6L 2WD (310Hp) 2014-16
- Porsche 970.2 Panamera 4 V6 3.6L 4WD (310Hp) 2014-16
Rather than replacing a mechanical engine component, XperTune modifies the software calibration within the vehicle's engine control unit (ECU). The tune optimises selected engine-management parameters to make better use of the engine's available performance while taking the individual vehicle and its modifications into account.
The supplied XperTune handheld device connects through the Porsche's OBD-II diagnostic port, allowing the factory ECU file to be read and a custom Fabspeed calibration to be installed without removing and shipping the ECU.
Fabspeed lists the 3.6L V6 at 296 HP / 295 TQ in standard form and 314 HP / 310 TQ with its tune. These are manufacturer-reported figures from a specific test vehicle; actual results will vary according to vehicle condition, specification, fuel, modifications and environmental conditions.
What This Product Does:
The ECU controls many of the functions required to operate the engine correctly.
Its software calibration determines how the engine-management system responds to operating conditions and driver inputs.
Fabspeed XperTune provides a vehicle-specific performance calibration intended to optimise the engine's operation for improved performance and drivability.
Depending on the vehicle and its configuration, the tune is designed to provide benefits such as:
- Increased horsepower
- Increased torque
- Improved throttle response
- Sharper engine response
- Improved power delivery
- Better use of supporting performance modifications
- More responsive overall driving characteristics
The calibration is created using information about the individual vehicle and its existing modifications.
Custom ECU Calibration:
XperTune is not simply a physical plug-in power module.
The handheld device is used to communicate with the factory ECU and install a custom software calibration.
The basic process involves:
- Connecting the XperTune device to the vehicle's OBD-II port.
- Reading the original ECU information.
- Transferring the factory file using a compatible Windows PC.
- Providing Fabspeed with the required vehicle and modification information.
- Receiving the custom calibration.
- Loading the tune onto the XperTune device.
- Flashing the new calibration to the vehicle through the OBD-II port.
This avoids the need to remove the ECU and send it away for conventional bench flashing.
XperTune Device Considerations:
- The XperTune handheld device is electronically paired, or "married," to the vehicle.
- Fabspeed states that the device can only be used with one vehicle.
- This is particularly important when purchasing, transferring or replacing tuning equipment.
- A device already paired with another vehicle should not be assumed to work with a different Panamera.
Why Upgrade To Fabspeed XperTune:
A healthy factory ECU does not need to have failed for XperTune to be installed.
This product is primarily a performance upgrade.
Reasons for upgrading include:
- Manufacturer-reported horsepower increase
- Manufacturer-reported torque increase
- Improved throttle response
- Improved engine response
- Custom calibration based on vehicle specification
- Support for compatible performance modifications
- OBD-II flashing
- No requirement to remove and mail the ECU
- Ability to restore the stock calibration
- Reusable access to the Fabspeed tune on the paired vehicle
- Porsche 996 GT3 MKI 1999-02
- Porsche 996 GT3 MKII 2003>>
The Fabspeed Porsche 996 GT3 Cat Bypass X-Pipe is a high-performance competition exhaust component designed to replace the factory catalytic converters with a freer-flowing X-pipe arrangement.
Fits:
- Porsche 996 GT3 MKI 1999-02
- Porsche 996 GT3 MKII 2003>>
Developed for track and competition-focused Porsche 996 GT3 applications, the system removes the restrictive catalytic-converter section and provides a more direct route for exhaust gases leaving the engine.
By reducing exhaust restriction and allowing gases from both cylinder banks to merge through the X-pipe, the system is designed to improve exhaust flow, sharpen throttle response, reduce weight and produce a considerably more aggressive GT3 exhaust note.
What This Product Does:
The original catalytic converters form part of the vehicle's emissions-control system.
While catalysts treat exhaust gases, their internal substrates also create resistance to exhaust flow.
The Fabspeed Cat Bypass X-Pipe removes this catalytic restriction and replaces it with freer-flowing exhaust pipework.
The system is designed to:
- Remove the restrictive factory catalytic converters
- Increase exhaust-gas flow
- Reduce exhaust backpressure
- Improve engine breathing
- Improve throttle response
- Increase horsepower and torque potential
- Reduce exhaust-system weight
- Increase exhaust volume
- Produce a more aggressive motorsport-inspired sound
Because the catalytic converters are removed, this is fundamentally different from a Sport Cat system.
X-Pipe Design:
An X-pipe connects the exhaust streams from the two cylinder banks.
Rather than keeping both exhaust paths completely separate, the crossover allows pressure pulses from each bank to interact.
A properly designed X-pipe can help:
- Balance exhaust pulses
- Improve gas-flow transitions
- Reduce turbulence
- Improve exhaust scavenging
- Support high-RPM performance
- Create a smoother, more exotic exhaust tone
This is particularly suited to the naturally aspirated, high-revving flat-six engine used in the 996 GT3.
Maximum Exhaust Flow:
Removing the catalytic substrates eliminates one of the major restrictions in the exhaust system.
This creates a substantially more open exhaust route.
Potential benefits include:
- Reduced exhaust backpressure
- Faster exhaust evacuation
- Improved engine breathing
- Sharper throttle response
- Stronger high-RPM performance
- Increased performance potential
Actual performance depends on the complete vehicle configuration.
Why Upgrading Matters:
The factory catalytic converters do not need to have failed for this component to be installed.
The Cat Bypass X-Pipe is primarily a competition performance upgrade.
Reasons for upgrading include:
- Maximum exhaust-gas flow
- Elimination of catalytic-converter restriction
- Reduced exhaust backpressure
- Improved throttle response potential
- Increased horsepower and torque potential
- Reduced exhaust-system weight
- More aggressive GT3 exhaust sound
- Improved high-RPM exhaust character
- X-pipe crossover design
- Track-focused configuration
It is particularly suited to vehicles where performance and exhaust flow take priority over road-use emissions requirements.
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.

- Porsche 944 Turbo 2.5L 8V 1989-91
The Fabspeed Porsche 944 Turbo 951 Sport Cat is a high-flow performance catalytic converter designed to reduce exhaust restriction while retaining catalytic exhaust treatment.
Fits:
- Porsche 944 Turbo 2.5L 8V 1985-88
- Porsche 944 Turbo 2.5L 8V 1989-91
Using a 200-cell high-flow catalyst combined with mandrel-bent T304L stainless-steel tubing, the Sport Cat provides a freer-flowing exhaust path than the restrictive original catalyst arrangement. On the turbocharged Porsche 944 Turbo / 951, reducing post-turbo exhaust restriction can improve exhaust flow, throttle response and overall performance while also producing a more defined performance exhaust note.
The Sport Cat is designed to work with the Fabspeed Downpipe. It can be purchased separately for vehicles already equipped with the appropriate Fabspeed downpipe or selected together with the downpipe as a complete configuration.
What This Product Does:
The catalytic converter forms part of the exhaust system and processes exhaust gases before they leave the vehicle.
A conventional catalyst contains a structured substrate coated with catalytic materials. As hot exhaust gases pass through this substrate, chemical reactions convert harmful pollutants into less harmful compounds.
The Fabspeed Sport Cat performs this basic catalytic function while using a high-flow 200-cell design intended to reduce restriction compared with the original catalyst arrangement.
It is designed to provide:
- Improved exhaust-gas flow
- Reduced post-turbo exhaust restriction
- Improved throttle response
- Increased horsepower and torque potential
- Reduced exhaust-system weight
- Moderate increase in exhaust volume
- More defined performance exhaust note
- Catalytic exhaust-gas treatment
200-Cell High-Flow Catalyst:
- The Fabspeed system uses a 200-cell high-flow catalytic converter.
- Cell count describes the density of the passages through the catalyst substrate. A performance-oriented 200-cell design provides relatively large passages for exhaust gases while maintaining the surface area required for catalytic reactions.
- Reducing restriction is particularly relevant to a turbocharged engine because exhaust gases leaving the turbocharger still need to travel efficiently through the remainder of the exhaust system.
- A freer-flowing post-turbo exhaust can therefore support improved engine and turbocharger response.
Performance Benefits:
Fabspeed lists manufacturer-reported figures of approximately:
Horsepower: +20 HP
Torque: +18 ft-lb
Weight Reduction: Approx. 12 lb
The system is also designed to improve throttle response.

It can therefore be ordered:
- As a Sport Cat for a vehicle already equipped with the compatible Fabspeed downpipe
- Together with the Fabspeed downpipe as a complete configuration
The existing exhaust configuration should be confirmed before ordering.
Why Upgrading Matters:
The Fabspeed Sport Cat is also a performance upgrade, so the original catalytic converter does not necessarily need to have failed before replacement.
Reasons for upgrading include:
- 200-cell high-flow catalyst
- Reduced post-turbo exhaust restriction
- Improved exhaust flow
- Improved throttle response
- Increased horsepower and torque potential
- Approx. 12 lb weight reduction

- Porsche 911 1987-1989 3.2L G50
Based on the European pre-muffler concept, this component replaces the original catalytic converter with a freer-flowing, resonated exhaust section. The result is reduced exhaust restriction, improved throttle response, reduced weight and a stronger air-cooled flat-six exhaust note.
Unlike a simple straight catalyst bypass pipe, the Fabspeed European Pre-Muffler incorporates a straight-through resonator with stainless-steel wool packing. This helps produce a deeper, more refined performance exhaust tone while reducing the harsh rasp often associated with completely straight-piped exhaust systems.
What This Product Does:
The pre-muffler replaces the factory catalytic converter section of the exhaust system.
Instead of forcing exhaust gases through the restrictive catalyst substrate, the Fabspeed pipe provides a freer-flowing route towards the rear muffler.
This is designed to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Reduce backpressure
- Improve throttle response
- Increase horsepower and torque potential
- Reduce exhaust-system weight
- Increase exhaust volume
- Enhance the classic air-cooled flat-six sound
Because the original catalytic converter is removed, the component no longer provides the emissions-treatment function of the factory catalyst.
Resonated European Design:
- Rather than using a completely empty straight pipe, Fabspeed incorporates a straight-through resonator.
- The resonator allows exhaust gases to travel through the system with minimal restriction while controlling some of the undesirable frequencies produced by an unrestricted exhaust.
- Its stainless-steel wool packing helps create a deeper, more purposeful exhaust character without the excessive rasp commonly associated with a basic straight catalyst-delete pipe.
Performance Benefits:
Fabspeed states that the European Pre-Muffler provides 16+ wheel horsepower and 15+ ft-lb of torque, together with significantly improved throttle response.
During Fabspeed DynoJet testing, peak curve gains of up to 21 WHP and 17 ft-lb at approximately 4,500 rpm were recorded, with maximum power increases of approximately 16 WHP and 16 ft-lb.
These are manufacturer-reported figures from a specific test vehicle and should not be considered guaranteed results for every Porsche 911.
Actual performance can vary depending on:
- Engine condition
- Engine specification
- Existing exhaust system
- Intake modifications
- Fuel system condition
- Ignition condition
- Engine tuning
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
This product is primarily a performance exhaust modification, rather than a routine service replacement.
The original catalyst does not need to have failed before the Fabspeed pre-muffler can be installed on a vehicle intended for appropriate competition or off-road use.
Reasons for upgrading include:
- Reduced exhaust restriction
- Improved exhaust flow
- Increased horsepower potential
- Increased torque potential
- Sharper throttle response
- Approx. 8 lb weight reduction
- Stronger air-cooled flat-six sound
