The Fabspeed Long Tube Competition Race Header System is a complete motorsport-focused exhaust upgrade developed for the Porsche 911 991.2 GT3 and GT3 RS.
Fits:
- Porsche 991.2 GT3 4.0L (500 Bhp) / GT3 RS 4.0L (520 Bhp) 2017-19
Designed for racing, track events and off-road competition use, the system combines high-flow long-tube headers with Burns Stainless merge collectors and integral side muffler bypass pipes equipped with premium Helical exhaust valves.
The system replaces the restrictive factory catalytic-converter-equipped header arrangement and provides a significantly freer-flowing exhaust route from the cylinders into the rear exhaust system.
By improving exhaust gas evacuation and managing exhaust pulses more effectively, the system is designed to improve throttle response, optimise high-RPM breathing and maximise the performance potential of Porsche's naturally aspirated 4.0-litre flat-six engine.
Fabspeed develops its long-tube systems using CAD design and incremental Dynojet testing. The current manufacturer listing does not specify a fixed horsepower or torque increase for this complete system, with both figures currently shown as TBD.

- Porsche 991.2 GT3 4.0L (500 Bhp) / GT3 RS 4.0L (520 Bhp) 2017-19
The Fabspeed Long Tube Race Headers are a competition-focused exhaust upgrade developed for naturally aspirated Porsche 911 GT3, GT3 RS and 911 R models of the 991 generation.
Fits:
- Porsche 991.1 GT3 3.8L (475 Bhp) 2014-16
- Porsche 991.2 GT3 4.0L (500 Bhp) 2017-19
Designed for circuit, motorsport and off-road applications, the system replaces the factory catalytic-converter-equipped headers with a carefully developed long-tube header arrangement engineered to improve exhaust scavenging, reduce restriction and maximise the breathing potential of Porsche's high-revving flat-six engine.
Fabspeed developed the system in conjunction with Burns Stainless, using motorsport-derived high-velocity merge collectors and long primary tubes to improve the way exhaust pulses leave each cylinder and combine within the exhaust system.
The headers are manufactured from T321 stainless steel, CNC mandrel bent and hand TIG welded with back-purging. T321 is particularly well suited to high-temperature motorsport exhaust applications because of its excellent resistance to repeated thermal cycling.
Fabspeed's current product listing quotes performance gains of approximately:
+19 HP
+13 lb-ft of torque
These are manufacturer-listed figures from specific testing and should not be regarded as guaranteed gains for every vehicle.
Because the system removes the original catalytic converters, it is specifically intended for closed-course competition and off-road use rather than public-road use.
What This Product Does:
The Long Tube Race Headers replace the original Porsche exhaust manifolds and catalytic-converter assemblies with a freer-flowing competition header system.
They are designed to:
- Improve exhaust gas evacuation from each cylinder.
- Reduce exhaust restriction.
- Improve exhaust pulse scavenging.
- Support increased horsepower and torque.
- Improve throttle response.
- Enhance high-RPM breathing.
- Complement the high-revving character of the GT3 engine.
- Produce a significantly more aggressive exhaust note.
- Reduce catalyst-related exhaust restriction.
- Support additional competition engine and exhaust modifications.
Symptoms Of Wear Or Failure:
Race headers are exposed to severe temperature and vibration.
Possible symptoms of deterioration include:
- Ticking noises from the exhaust.
- Blowing noises during acceleration.
- Visible exhaust leaks.
- Soot around welds or flanges.
- Cracked primary tubes.
- Cracked welds.
- Damaged collectors.
- Loose slip joints.
- Increased exhaust smell.
- Metallic rattling.
- Exhaust vibration.
- Reduced performance.
- Exhaust noise changing unexpectedly.
Why Replacement Matters:
Replacing cracked or damaged headers helps restore:
- Correct exhaust sealing.
- Intended exhaust scavenging.
- Smooth exhaust flow.
- Proper collector operation.
- Safe containment of hot exhaust gases.
- Structural integrity.
- Consistent engine performance.
For track-driven cars, header condition should be checked regularly because operating temperatures and mechanical loads can be considerably greater than during normal road driving.

As many GT3 owners know, the OEM mufflers are prone to cracking, breaking and blowing out, particularly the titanium mufflers on GT3RS cars. Fabspeed Motorsport Engineers design a GT3 primary muffler replacement that not only fixed that issue but also greatly improved on the OEM design in multiple measurable ways. Using our 30+ years of air and water-cooled experience, we took the valve open tubing to 2.75in / 70mm which is the optimal diameter for GT3 engines to have low restriction but maintain high velocity and high RPM GT3 pitch for the signature GT3 CUP car sound. Then, we implemented our signature investment cast 70mm 2.75" X-Pipe for optimal exhaust scavenging and maximum volumetric efficiency. The X merges the two cylinder banks without creating any restriction in exhaust flow. To maintain the factory muffler’s exhaust note and lack of drone, we mimicked Porsche’s 7 chamber design. This makes for a completely drone free muffler, even when running cat-less race headers! Using GT3 headers with cats or Fabspeed headers with HJS German EPA approved catalytic converters along with Fabspeed GT3 Side Muffler Muffler Bypass Pipes for the ultimate emissions compliant lightweight GT3 exhaust. Fabspeed's GT3 center muffler is guaranteed to NEVER BREAK or fail- and OUTPERFORM any other aftermarket GT3 center muffler. 100% made in house at Fabspeed.
SOUND:
This muffler will have a very similar tone to the OEM muffler, however, it will be a bit louder with PSE turned on. It will also sound a bit smoother and higher pitched thanks to our signature X-pipe.
POWER:
On our 991.1 GT3RS test car, paired with our Side Muffler Muffler Bypass Pipes, the Rennsport Muffler picked up an impressive 27 ft/lbs of TQ down low at 3,200 RPM. From 2,900 RPM all the way to 5,700 RPM it picks up =12 horsepower or more, and peak power at the wheels is up from 446 to 454! That’s a gain of over 12 HP at the crank- from simply swapping out the fragile restrictive OEM Porsche 997GT3 to the very latest 991.2 GT3 Titanium OEM factory mufflers. BEST ADVICE- but and install a Fabspeed GT3 center muffler and SAVE you fragile OEM GT3 muffler for Concours shows and restoration. All GT3 OEM mufflers BREAK & EXPLODE when driven long and hard enough.
NOTE:
• Requires OEM gaskets and hardware to be reused
• If they are not available here are the necessary part numbers.
