Fabspeed Center Muffler Bypass X-Pipe. Porsche 991.2 GT2 RS (2018+) › FSPOR9912GT2RSCMX
- Porsche 991.2 GT2 RS 3.8L PDK (700 bhp) 2018-19
The Fabspeed Center Muffler Bypass X-Pipe is a high-performance exhaust upgrade developed specifically for the Porsche 911 991.2 GT2 RS from 2018 onward, including Weissach and Manthey MR-equipped cars.
Fits:
- Porsche 991.2 GT2 RS 3.8L PDK (700 bhp) 2018-19
Designed to replace the factory titanium centre muffler, the system provides a freer-flowing exhaust path while retaining the vehicle's original catalytic converters.
At the centre of the system is Fabspeed's investment-cast X-pipe. The crossover allows exhaust gases from the two sides of the engine to merge through a carefully shaped central opening, helping reduce restriction, balance exhaust flow and produce a stronger, more exotic exhaust note.
The system is manufactured from 14–16 gauge T304 stainless steel with larger-diameter CNC mandrel-bent tubing. It provides a durable alternative to the original titanium centre muffler while increasing exhaust sound and supporting improved throttle response and performance.
Fabspeed currently lists a +20 HP performance gain for this product. Actual gains can vary according to vehicle condition, fuel, environmental conditions and other modifications.
What This Product Does:
The Fabspeed X-pipe replaces the original centre muffler in the rear exhaust system.
It is designed to:
- Reduce restriction through the centre exhaust section.
- Improve exhaust gas flow.
- Replace the factory titanium centre muffler.
- Increase exhaust volume.
- Produce a more dynamic GT2 RS exhaust note.
- Improve throttle response.
- Support increased engine performance.
- Retain the original catalytic converters.
- Maintain a catalyst-equipped exhaust configuration.
- Provide a durable stainless-steel replacement for the factory centre muffler.
- Allow straightforward installation and removal using the existing clamped exhaust arrangement.
Symptoms Of Wear Or Failure:
Possible symptoms of deterioration in the original centre muffler include:
- Metallic rattling.
- Exhaust blowing noises.
- Cracks around welds.
- Visible exhaust leakage.
- Soot around damaged joints.
- Increased exhaust noise.
- Muffler casing damage.
- Loose internal components.
- Exhaust vibration.
- Exhaust hanging incorrectly.
- Damaged inlet or outlet connections.
- Exhaust contacting surrounding components.
- Heat-related structural deterioration.
A damaged muffler should be inspected before continued high-load or track use.
Why Replacement Matters:
Replacing a damaged or restrictive centre muffler section helps restore:
- Correct exhaust sealing.
- Safe routing of hot exhaust gases.
- Proper exhaust alignment.
- Structural integrity.
- Consistent exhaust flow.
- Reliable mounting.
Upgrading to the Fabspeed X-pipe additionally provides:
- Increased exhaust sound.
- Reduced centre-section restriction.
- Improved throttle response.
- A more performance-focused exhaust character.
- Retention of the factory catalytic converters.
