Fabspeed Porsche 992 GT3 / GT3 RS Valvetronic Nordschleife Cat-Back Exhaust System (2022+)

The Fabspeed Motorsport Valvetronic Nordschleife Cat-Back Exhaust System gives the 992 GT3/ GT3RS a truly exotic sports car sound, all while retaining the functionality of PSE, Porsche Sport Exhaust valvetronic push button system. Our design process started with 3D laser scanning the entire OEM exhaust system and underside of the GT3 flat 6 engine using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then CAD designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM Porsche Motorsport standards. After multiple revisions for Sound Quality and ACTUAL incremental dyno testing we decided to use our signature cast 70mm 2.75" X-Pipe to tie the two Flat-Six cylinder banks together for exhaust scavenging and to defeat resonance. The exhaust valves are made by Helical Limited in the United Kingdom. These are the WORLD's finest Aerospace quality exhaust valves.   Helical ISO 9001 certified valves are the same one
