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.

Fabspeed Competition Muffler Outlets W / Adjustable Turndowns. Porsche 996 GT3

FSPOR996GT3CMO

Product Information

Fabspeed Competition Muffler Outlets W / Adjustable Turndowns.

The Fabspeed Porsche 996 GT3 Competition Muffler Outlets with Adjustable Turndowns are a specialist exhaust upgrade designed to help Porsche 911 GT3 owners manage exhaust noise at track days, racing events and motorsport venues with strict decibel limits.

Fits:

Porsche 996 GT3 MKI 1999-02
Porsche 996 GT3 MKII 2003>>

Developed for Porsche 996 GT3 models manufactured between 1999 and 2005, these competition exhaust outlets replace the factory exhaust tips with adjustable stainless steel turndowns that allow the direction of exhaust discharge to be changed.

The Porsche 996 GT3 features a naturally aspirated 3.6-litre flat-six engine renowned for its high-revving character and distinctive motorsport-inspired exhaust note.

While this sound is an important part of the GT3 driving experience, high-performance exhaust systems can produce noise levels that exceed the limits imposed by certain racing circuits and track-day organisers.

Many motorsport venues use static or drive-by sound monitoring to ensure that vehicles remain within permitted noise levels. Cars exceeding these limits may be refused access to the circuit or required to stop participating.

Fabspeed developed the Competition Muffler Outlets to provide a practical method of redirecting exhaust noise without requiring the driver to replace the complete exhaust system.

The adjustable turndown design allows the exhaust outlets to be rotated, directing gases and sound downwards or towards another suitable angle rather than straight out of the rear of the vehicle.

This change in direction can alter the way exhaust sound reaches external measurement equipment, potentially reducing measured noise at particular monitoring positions.

Manufactured from T304L stainless steel, the competition outlets are designed to withstand the high temperatures and operating conditions associated with performance exhaust systems.

The product uses a bolt-on installation arrangement, with the required clamps and mounting hardware supplied.

No cutting or welding is required when fitting the outlets to the corresponding Porsche 996 GT3 exhaust arrangement.

Unlike a complete replacement silencer, these outlets do not introduce a new muffler or significant additional sound-absorbing material.

Their primary purpose is to redirect exhaust sound, rather than to substantially reduce the total acoustic energy produced by the engine.

They are particularly useful for Porsche owners who want to retain their existing exhaust system while gaining additional flexibility for track events.

What This Product Does:
The Fabspeed Competition Muffler Outlets replace the original rear exhaust tips with adjustable outlets designed to change the direction of exhaust gas discharge.

Their primary functions include:

Redirect Exhaust Sound: Change the angle at which exhaust noise leaves the rear of the vehicle.
Support Track Noise Management: Help reduce sound exposure at particular external measurement positions.
Provide Adjustable Exhaust Direction: Allow the turndown outlets to be rotated to an appropriate position.
Direct Exhaust Towards the Ground: Enable downward-facing exhaust discharge where suitable.
Offer Alternative Outlet Angles: Allow the driver or technician to adjust the orientation according to the intended application.
Support Motorsport Use: Provide additional flexibility for vehicles attending noise-controlled circuits.
Replace Factory Exhaust Tips: Fit in place of the original exhaust outlet components.

Common signs that the existing exhaust outlet arrangement requires attention include:

Exhaust outlets moving when inspected.
Metallic rattling from the rear of the vehicle.
Unevenly positioned exhaust tips.
Loose mounting clamps.
Exhaust tips contacting surrounding components.
Heavy rust around mounting connections.
Corroded clamps or fasteners.
Surface deterioration.
Weak or damaged welds.
Difficulty removing or adjusting the outlets.
Visible cracks.
Deformed or bent outlets.

Porsche 991.2 Turbo S Cabriolet 3.8L (580 Bhp) 2017-19

Kit Includes:

Supersport X-Pipe Exhaust
Sport Headers
BCM F1 Replacement Air Filter
XperTune Performance Software

Developed for the 3.8-litre twin-turbocharged flat-six engine, this package combines Fabspeed's Supersport X-Pipe exhaust, performance sport headers, upgraded air filtration and available XperTune ECU software into an integrated performance solution.

The Porsche 991.2 Turbo and Turbo S deliver exceptional performance in standard form. However, their factory exhaust systems are engineered to balance sound, emissions, refinement and everyday usability.

Fabspeed's Supersport Performance Package is designed for drivers seeking a more distinctive exhaust note and a performance-focused configuration while retaining the ability to select components suited to their intended application.

At the centre of the package is the Fabspeed Supersport X-Pipe Exhaust System, engineered to provide a deeper, more aggressive exhaust character than the original factory system.

The package also includes Fabspeed Sport Headers, designed to optimise the flow of exhaust gases from the engine towards the turbochargers.

Improved exhaust flow may help reduce exhaust restriction, support turbocharger response and contribute to stronger acceleration when combined with the appropriate engine calibration.

A BMC F1 replacement air filter supports the intake side of the engine by providing an alternative performance filtration element within the corresponding factory intake arrangement.

The package is available with Fabspeed's XperTune performance software, which calibrates the engine management system to complement the installed hardware.

The system is manufactured using high-quality 14–16 gauge T304L stainless steel with CNC mandrel-bent tubing for consistent internal pipe dimensions and durable construction.

Fabspeed publishes headline gains of up to 135 hp and 160 lb-ft of torque, together with an approximate 15 lb weight reduction, based on its specified testing and package configuration.

These are manufacturer-reported figures and should not be interpreted as guaranteed improvements for every vehicle.

Whether developing a more responsive road-oriented Porsche or preparing a track-focused 991.2 Turbo, the Supersport Performance Package provides an integrated upgrade for owners seeking a stronger exhaust character and increased performance potential.

What This Product Does:
The Fabspeed Supersport Performance Package upgrades several aspects of the engine's intake, exhaust and performance calibration.

Its primary functions include:

Improves Exhaust Flow: The performance X-pipe and headers are designed to reduce unnecessary restrictions in the exhaust system.
