Product Details:

Transform your GT4 RS’s exhaust note. Our X-pipe design gives the GT4 RS the same high pitched wail as 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.

Fabspeed's 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. Fabspeed then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing Fabspeed decided to use our signature cast X-Pipe to tie the two cylinder banks together for exhaust scavenging and to defeat resonance. They also went to great lengths to eliminate drone on this exhaust, utilizing helmholtz resonator technology to cancel out unwanted frequencies that “drone.”

SOUND:

Wondering why your GT4 RS doesn’t have the same high pitched scream of the GT3? Fabspeed's Valvetronic X-Pipe is the solution! Fabspeed's 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.

POWER:

Comparing Fabspeed's development car equipped with the Fabspeed Over Axle Link Pipes, their Vavletronic X-Pipe added 6 WHP at 8100 RPM and 9 ft/lbs of TQ at 3500 RPM.
