Introducing the much anticipated JHMotorsports 2.75 Inch Cat-Back Exhaust System for the C6-S6 5.2L V10 FSI!!



Why 2.75 Inch piping diameter? After much research, calculations, testing and development we found that based on the 5.2L V10 FSI engine's demands, 2.75 Inch piping diameter is the optimal size. With a 2.5 inch or smaller exhaust you end up choking off the V10. We have also found with a 2.75 inch cat back that torque is not sacrificed for power gains in the top end of the RPM band.


Why an X-pipe? Naturally Aspirated V10s always make more power with an X-pipe. The location and size of the X-Pipe in the JHM C6-S6 5.2L V10 FSI Cat-Back Exhaust System has been meticulously researched and developed to produce the best scavenging of the exhaust pulses coming from either side of the motor. The location of our X-Pipe also gives the motor a cleaner, more refined tone.

If you own a S6, you NEED this in your life!
I have a 2008 Audi S6 and primarily purchased the vehicle for the Lamborghini inspired v10. Although the car has S6 Luxury, it's severely lacking in S6 performance, until JHM came along...

This is how the car should have came from the factory or at least a performance package from the factory that included the JHM Exhaust and Tune. The car finally has that exotic sound and performance you expect from a V10 without being overly loud or drone. By far one of the best sounding car I've ever owned or driven to date.

Product Questions

I recently purchased a 2008 Audi S6 with the V10. My research into how to best maintain and improve upon the platform have led me to your products. I'm really interested in your exhaust system. What should I look for in a local dealer to have the cat-back system installed? Is it something that one could install at home?
