Introducing the much anticipated JHMotorsports 2.75 Inch Downpipe Pair for the B7-RS4 4.2L FSI 32v V8!!!
Why 2.75 Inch piping diameter? After much research, calculations, testing and development we found that based on the 4.2L 32v V8 engine's demands, 2.75 Inch piping diameter is the optimal size. With a 2.5 inch exhaust you end up choking off the RS4's free spinning and high-revving V8. We have also found with a 2.75 inch downpipes that torque is not sacrificed for power gains in the top end of the RPM band.
JHM B7-RS4 2.75 Inch Exhaust System Build Quality: Our B7-RS4 Exhaust Systems are made entirely of stainless steel and crafted with the utmost attention to detail:
Cat-Back Connection Type: We can make our JHM 2.75" Stainless Steel Downpipes for fitment to a stock cat-back or we can build it to connect to our JHM 2.75" Cat-Back Exhaust. Select your current configuration from the dropdowns below.

- Very Impressive
Looking very much fwd to get these installed and dumped out the old sportscats from another brand that looked bad.
Piping looked impressive and result in response and power was very good. And sound from the rest of the piping was extremely good, no spitting or machine-gun sort of thing, just nice deep V8 that screams up as it revs. Supersprint x-tube and rear ends together with these pipes with 300 cell cats can absolutely be recommended.
One thing to mentioned; yaw marks on the cats from bench wise didn't look professional Review by Roger (Posted on 3/18/2019)
