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.

Designed for owners who want significantly improved exhaust flow and a more aggressive sound while retaining catalytic converters, the system replaces the restrictive factory 700-cell ceramic catalysts and OEM titanium centre muffler with large German HJS 200-cell high-flow catalytic converters and direct rear exhaust outlets.
Unlike Fabspeed's valved GT2 RS sport-cat system, this version contains no exhaust valves. Exhaust gases therefore follow a direct, unrestricted path through the high-flow catalysts and towards the rear outlets at all times.
The HJS catalysts use a high-performance tri-metallic substrate and are designed to provide very high exhaust flow while maintaining catalytic treatment. Fabspeed states that the 200 CPSI HJS cores can flow approximately 90–93% of a straight pipe in suitable applications.
The system is fabricated from 14–16 gauge CNC mandrel-bent T304 stainless steel and includes both angle-cut outlets and slip-on 90-degree turn-down outlets.
Fabspeed currently reports hardware-only gains of:
+7 WHP
+10 lb-ft of torque
Approximately +8.5 HP and +12 lb-ft at the engine
Approximately 12 lb weight reduction
When combined with Fabspeed ECU tuning, the manufacturer also states that its test configuration has produced over 740 HP at the wheels and approximately 850–888 HP at the crank on pump fuel.
Actual performance will vary according to vehicle condition, fuel, calibration, environmental conditions and other modifications.
