Former Vendor
Grant69283: Your GTS sounds like a beast
. After we did the install me and Joey burned up a half tank of gas listening to that sound.
Today we dyno tested a 2008 Porsche Cayenne GTS with the stock secondary cats and with our secondary catbypass pipes. We want to thank Alex Hilgetag, the General Manager of Princeton Porsche for allowing us to use his Cayenne for the performance testing and the video capture. The Cayenne GTS, euipped with Fabspeed's 2008 Cayenne S catbypass pipes increase power by +11 HP and +12 ft/lbs of torque. The catbypass pipes enhance throttle response and accleration throughout the RPM's much quicker than the stock setup. Turn your speakers up and listen to the aggressive sound only from Fabspeed Motorsports!!!

Wow...when it rains it pours with GTS goodness.
Great sound clip.
With sport mode off and windows up do you hear much?
Not all my clients are car enthusiasts (but they should be!)
Thanks again.

with sport mode OFF it seems like "sport" still kicks in around 4,000 RPM if i have it hammered. But without sport on there isn't much difference over stock.

They are working on it so no numbers on it yet. I'm guessing between 20-30 increase.
