Porsche 718 GT4 RS 2022+ Fabspeed Valvetronic X-Pipe Cat-Back Exhaust System – FSPOR718GT4VLV

Description

Transform your GT4 RS’s exhaust note and ADD significant power versus the stock GT4 RS rear exhaust. FABSPEED’s proprietary  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.

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. After multiple revisions for sound and 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 valvetronic 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 Valvetronic 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.

POWER:

Comparing our development car equipped with our Over Axle Link Pipes, our Vavled X-Pipe added +7.5HP (+6.2 HP at the rear wheels)  at 8100 RPM and +11 ft/lbs of TQ at 3500 RPM. WE designed and DYNO developed multiple systems BEFORE we settled on the very best system in terms of sound and horsepower. Trust Fabspeed with over 30 years or experience!
