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.

The Fabspeed XperTune Performance Software is a custom ECU calibration upgrade designed for the 2008–2010 Porsche 957 Cayenne Turbo and Turbo S 4.8L.
Fits:
- Porsche 957 Cayenne Turbo / Turbo S 4.8L 2008-10
Rather than replacing a mechanical engine component, XperTune modifies the calibration within the vehicle's engine control unit (ECU) to optimise performance. The tune is developed around the individual vehicle and its modifications, with the aim of increasing horsepower and torque while improving throttle response and overall drivability.
The package includes a MyGenius handheld tuning device, allowing the vehicle's factory ECU data to be read through the OBD-II diagnostic port. This information is supplied to Fabspeed, which creates a custom calibration for the vehicle. The completed tune is then loaded onto the MyGenius device and flashed back to the Cayenne through the OBD-II port.
The original factory calibration can also be restored using the handheld device without removing or mailing the ECU.
What This Product Does:
The ECU controls many of the operating strategies used by the engine.
On a turbocharged performance engine, these can include parameters associated with:
- Boost control
- Ignition timing
- Fuel delivery
- Throttle response
- Torque management
- Engine load
- Power delivery
Performance ECU software recalibrates selected parameters to make better use of the engine's performance capability.
The Fabspeed calibration is developed using information from the individual vehicle, allowing the tune to account for the Cayenne's existing specification and performance modifications.
Custom Calibration:
The Fabspeed tune is not simply described as a generic file installed without reference to the vehicle.
The tuning process uses the factory ECU data together with information supplied about the vehicle and its modifications.
This allows Fabspeed to prepare a calibration for the specific setup.
Relevant modifications may include changes to:
- Intake system
- Exhaust system
- Intercooling
- Other compatible performance hardware
Accurate vehicle and modification information should be supplied when requesting the calibration.
MyGenius Handheld Tuner:
The included MyGenius handheld device allows the ECU tuning process to be carried out through the vehicle's OBD-II diagnostic connection.
The normal process is:
- Read the vehicle's stock ECU data through the OBD-II port using MyGenius.
- Connect MyGenius to a Windows computer.
- Supply the factory ECU information and vehicle details to Fabspeed.
- Fabspeed develops the custom tune.
- Load the completed calibration onto the MyGenius device.
- Flash the new calibration to the vehicle through the OBD-II port.
This eliminates the need to remove and mail the ECU for most installations.
Why Upgrading Matters:
The original ECU software does not need to be faulty before installing XperTune.
This product is primarily a performance upgrade.
Reasons for upgrading include:
- Increased horsepower potential
- Increased torque
- Improved throttle response
- Stronger acceleration
- Improved mid-range performance
- Custom calibration for the vehicle

- Porsche Boxster 986 2.5L 1997-99
The Fabspeed Porsche 986 Boxster Primary Sport Catalytic Converters are high-flow replacement catalysts designed for 1997–1999 Porsche 986 Boxster and Boxster S models.
Fits:
- Porsche Boxster 986 2.5L 1997-99
Designed to replace the more restrictive factory catalytic converters, these performance catalysts improve exhaust-gas flow while retaining catalytic converter functionality. The result is a more performance-oriented exhaust path designed to improve throttle response, support increased power potential and enhance the naturally aspirated Porsche flat-six exhaust note.
Fabspeed uses HJS/EMITEC high-flow catalytic converter technology, with the manufacturer specifying a 200 CPSI (cells per square inch) catalyst design. Fabspeed states that these catalysts can flow approximately 90–93% of the volume of a straight pipe in many applications while continuing to provide exhaust-gas treatment.
The converters are designed as a direct bolt-on replacement for the original catalytic converters, making them suitable for use with the factory OEM-style muffler or aftermarket exhaust systems designed to accept the original Porsche catalytic converter arrangement.
What This Product Does:
Catalytic converters form part of the vehicle's exhaust system and are designed to chemically convert harmful exhaust pollutants into less harmful compounds before gases leave the tailpipe.
However, exhaust gases must pass through a catalyst substrate, which creates some resistance to flow.
The Fabspeed Primary Sport Catalytic Converters use a high-flow catalyst design intended to reduce this restriction compared with the original factory catalysts.
Potential benefits include:
- Improved exhaust flow
- Reduced exhaust restriction
- Improved throttle response
- Increased performance potential
- Reduced weight compared with the original catalysts
- Enhanced flat-six exhaust sound
- Retained catalytic converter functionality
200CPSI High-Flow Catalyst Design:
- Catalytic converter density is commonly described in cells per square inch (CPSI).
- A performance-oriented 200 CPSI catalyst provides a relatively open exhaust path while maintaining the large internal surface area required for catalytic exhaust-gas treatment.
- Fabspeed states that its HJS/EMITEC 200 CPSI catalysts can flow approximately 90–93% of a straight pipe in many applications.
- This high-flow construction is designed to provide a balance between exhaust performance and catalyst functionality.
Performance:
Fabspeed states that these Sport Catalytic Converters improve power and throttle response, but the current product listing does not publish specific numerical gains.
The manufacturer currently lists:
Horsepower: TBD
Torque: TBD
Weight: TBD
Specific horsepower, torque or weight-saving figures should therefore not be assumed.
Actual performance will depend on factors including:
- Engine condition
- Existing exhaust configuration
- Rear muffler system
- Intake modifications
- ECU calibration
- Fuel quality
- Ambient conditions
- Testing equipment
- Testing methodology
Why Upgrading Matters:
The original catalytic converters do not have to be faulty before fitting the Fabspeed Sport Catalytic Converters.
They can also be installed as a performance upgrade.
Reasons for upgrading include:
- High-flow 200 CPSI catalyst design
- HJS/EMITEC catalyst technology
- Reduced exhaust restriction
- Improved exhaust flow
- Improved throttle response

- Porsche Boxster S 986 3.2L 2003-04
Manufactured from T304L stainless steel with CNC mandrel-bent tubing, the bypass pipes replace the original secondary catalysts with freer-flowing straight-through exhaust sections. This reduces exhaust restriction and weight while producing a more pronounced flat-six exhaust note and improved throttle response.
Fabspeed reports an increase of 8 wheel horsepower together with a substantial 25 lb (approximately 11.3 kg) weight reduction compared with the factory secondary catalytic converters. These are manufacturer-reported figures, and actual results can vary according to vehicle condition, specification and testing conditions.
These pipes are designed for use with the factory OEM-style muffler and install as a bolt-on replacement without cutting or welding.
What This Product Does:
The factory secondary catalytic converters form part of the Porsche 986 exhaust system and create a degree of restriction as exhaust gases pass through their internal catalyst substrates.
The Fabspeed Secondary Cat Bypass Pipes remove these secondary catalysts and replace them with straight-through exhaust tubing.
This creates a less restrictive path for exhaust gases travelling from the engine toward the rear muffler.
The upgrade is designed to provide:
- Reduced exhaust restriction
- Reduced backpressure
- Improved exhaust flow
- Improved throttle response
- Increased horsepower potential
- Reduced exhaust-system weight
- More aggressive exhaust sound
- Improved flat-six exhaust character
Removes The Factory Secondary Catalytic Converters:
- The principal function of this product is to replace the original secondary catalytic converters.
- Instead of forcing exhaust gases through the catalyst substrates, the bypass pipes provide a direct, straight-through path.
- This makes the system less restrictive and substantially lighter than the original catalyst assemblies.
- Because the secondary catalytic converters are removed completely, these pipes are intended for competition, closed-course and off-road applications rather than normal emissions-controlled road use.
Why Upgrading Matters:
The factory secondary catalytic converters do not need to have failed before installing this product.
These bypass pipes are primarily a performance, weight-saving and sound upgrade for competition-oriented vehicles.
Reasons for upgrading include:
- Removes restrictive secondary catalytic converters
- Straight-through exhaust path
- Reduced exhaust backpressure
- Improved exhaust flow
- Manufacturer-reported +8 WHP
- Improved throttle response
- Approximately 25 lb weight reduction
- Enhanced flat-six exhaust note
- T304L stainless-steel construction
- CNC mandrel-bent tubing
- Bolt-on installation
- No cutting or welding required
- Designed specifically for 2000–2004 Porsche 986 models
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.

The Fabspeed Porsche 986 Boxster Race Headers are a competition-focused exhaust upgrade designed for maximum exhaust flow, improved scavenging, reduced restriction and sharper engine response on 2000–2004 Porsche 986.2 Boxster and Boxster S models.
Fits:
- Porsche Boxster 986 2.7L 2000-02
- Porsche Boxster S 986 3.2L 2000-02
- Porsche Boxster 986 2.7L 2003-04
- Porsche Boxster S 986 3.2L 2003-04
Unlike Fabspeed's Sport Headers, these Race Headers do not contain catalytic converters. They replace the factory Porsche headers and their integrated primary catalysts with free-flowing equal-length headers, making them intended specifically for closed-course competition, race and off-road applications.
Constructed from equal-length T304 stainless-steel CNC mandrel-bent tubing, the headers use F1-style merge collectors to improve exhaust-gas velocity and scavenging. They can be used with the factory rear muffler or compatible aftermarket cat-back exhaust systems designed around the OEM mounting arrangement.
What This Product Does:
Headers collect exhaust gases as they leave the engine's cylinder heads and direct them into the remainder of the exhaust system.
The design, length and geometry of the individual primary tubes influence how efficiently these gases leave each cylinder.
The Fabspeed Race Headers replace the original catalyst-equipped manifolds with a freer-flowing, equal-length arrangement.
They are designed to provide:
- Maximum exhaust-gas flow
- Reduced exhaust restriction
- Reduced backpressure
- Improved exhaust scavenging
- Improved cylinder evacuation
- Increased performance potential
- Sharper throttle response
- Improved high-RPM breathing
- Reduced exhaust-system weight
- More aggressive flat-six exhaust sound
Removes The Factory Catalytic Converters:
- On 2000–2004 Porsche 986 Boxster models, the factory headers incorporate primary catalytic converters.
- The Fabspeed Race Headers remove these catalysts entirely.
- This creates a substantially less restrictive exhaust path but also means the product is fundamentally different from a street-oriented catalyst-equipped replacement header.
- The Race Headers are intended for vehicles where maximum exhaust flow is prioritised over emissions-system compatibility.
Why Upgrading Matters:
The factory headers do not need to have failed before installing this product.
These Race Headers are primarily a competition performance upgrade.
Reasons for upgrading include:
- Removes restrictive OEM catalytic converters
- Maximum exhaust-flow design
- Equal-length primary tubes
- T304 stainless-steel construction
- CNC mandrel-bent tubing
- F1-style merge collectors

The headers use equal-length CNC mandrel-bent primary tubes combined with F1-style high-velocity merge collectors. This configuration is designed to improve the way exhaust gases leave each cylinder and merge into the exhaust system, reducing unnecessary restriction and supporting more efficient engine breathing.
2000–2004 Porsche 986 Boxster / Boxster S: The original headers incorporate primary catalytic converters. Fabspeed therefore supplies these applications with 200-cell HJS Sport Catalytic Converters.
Fabspeed reports +8 wheel horsepower and +4 lb-ft of torque when the Sport Headers are installed with the Fabspeed Maxflo Performance Exhaust System. These are manufacturer-reported figures from a specific vehicle and are not guaranteed results for every application.
What This Product Does:
Exhaust headers collect combustion gases as they leave the engine's cylinder heads and direct them into the remainder of the exhaust system.
The design and length of the individual primary tubes influence how efficiently these exhaust pulses leave the cylinders.
The Fabspeed Sport Headers are designed to improve this process through equal-length primary tubing and high-velocity merge collectors.
Potential benefits include:
- Improved exhaust flow
- Improved exhaust scavenging
- Reduced exhaust restriction
- Improved cylinder evacuation
