Transform your GT4 RS and SPYDER RS exhaust note and ADD significant power versus the stock GT4 RS, Spyder RS rear exhaust. FABSPEED's proprietary  X-pipe design gives the RS models a much better high pitched wail than the GT3 and it’s totally plug-and-play with the factory exhaust valve system so you can quiet down the exhaust using the factory PSE button.  

Our design process started with 3D scanning the entire OEM exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. WE ACTUALLY and TRULY do all these FUNCTIONS in house at Fabspeed VERSUS local and other global competitors! After multiple revisions for sound and ACTUAL dyno testing we decided to use our signature investment cast  X-Pipe to tie the  FLAT 6 engine's two separate Right & Left cylinder banks together for exhaust scavenging and to defeat resonance. We also went to great lengths to eliminate drone on this exhaust, utilizing helmholtz resonator technology to cancel out unwanted frequencies that “drone.” Porsche GT4RS and SPYDER RS owners and shops- the FABSPEED GT4RS rear Valved is 100% guaranteed to be the best sounding, most reliable and most powerful system available. 

SOUND:

Wondering why your GT4 RS doesn’t have the same high pitched scream of the GT3? Our Valved X-Pipe is the solution! Our X-pipe design merges the two exhaust banks for an intoxicating 9000 RPM symphony. Even though this system will net you a significant increase in volume over stock, the valved design allows you to control the volume with the factory PSE (Porsche Sport Exhaust) button, quieting the exhaust note for a drone free driving experience. Fabspeed titanium mandrel bent tubing in long sections is 100% much better QUALITY than any Cheap Chinese PIE-CUT multiple welded together "lobster tail pie cut garbage exhaust" PIE CUT lobster tail titanium exhaust i INDICATIVE of super CHEAP alibaba nonsense and RUN AWAY from any piece cut exhaust systems regardless of internet HYPE.

POWER

Comparing our development car equipped with our Over Axle Link Pipes, our Valved X-Pipe added +7.5HP (+6.2 HP at the rear wheels)  at 8100 RPM and +11 ft/lbs of TQ at 3500 RPM.
