We just installed our Fabspeed 2ndary Catbypass Pipes, BMC Air Filters and the EVOMSit ECU tune on a 2008 Cayenne GTS. He liked the way it sounded already just wanted a little more rumble out of it and I told him this is the route to go for all GTS owners. The installation took about 2 hours to do all three items and bolted right up with an OEM caliber fit.

The big power gains on this car, are eliminating the Stock 2ndary 500 cell catalytic converters because of their size and restriction. Check the pictures below of the new catbypass pipes installed. They are simple and easy install and really make a noticeable difference. The Catbypass pipes help improve the aggressive sound and also make more power. When done together with the BMC Air Filters and the EVOMSit Tune, the combination really improves the throttle response, horsepower and overall feel of the Cayenne.

I cant repeat how deep and aggressive it sounds outside but very subtle inside the car. The customer loves the sound and power increase and thats what matters. PM or Email me if you have any questions and I will offer a discount to all Teamspeed members.
Thanks,
