Fabspeed Porsche 718 GT4 RS Valvetronic X-Pipe Cat-Back Exhaust System (2022+)

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
