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.
