The Fabspeed Motorsport Valvetronic Titanium 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). 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 cast 70mm 2.75" X-Pipe to tie the two cylinder banks together for exhaust scavenging and to defeat resonance. The exhaust valves are made by Helical Limited in the United Kingdom. These ISO 9001-certified valves are the same ones Ferrari, McLaren, Aston Martin and Porsche use on their GT cars. The piping is mandrel bent from Titanium, and you have five different tip options to choose from.


With PSE off our Valvetronic exhaust gives a nice subtle increase in volume. With PSE on it turns the 4.0L's exhaust note into a truly exotic sound with a significant increase in volume. The exhaust note changes from the smooth purr of the OEM exhaust to the aggressive race-bred snarl of a 911 CUP car. (If you need to cut down on how loud your exhaust is because of race track rules, we sell turn down tips that cut 3-6db of exhaust SPL.)


This system improves Porsche’s design by increasing pipe diameter from 2.5 in to 2.75 in and using our signature investment cast X-pipe instead of the factory H-Pipe. On our DynoJet we saw +17.5 crank HP or +14 whp at 4200 RPM and a healthy dose of torque down low at 4200 RPM gaining 17 ft/lbs of tq. Significant power gains that you can feel by the seat of your pants and also major rear weight savings. MORE POWER and the WORLD'S VERY BEST Sports Car sound 100% guaranteed and BETTER than any other competitors’ systems! Do not look any further if you want the very best.
