Introducing the JHM B8-RS5 4.2L FSI V8 2.75" Performance Race Header Modification!
Remove your restrictive and failure-prone OEM Catalyst with our JHM 2.75" Performance Race Header Modification. So far, we have yet to see a catalyst that isn't breaking apart.

With our smooth-flowing transition collectors, your B8-B8.5 RS4 and RS5 4.2L will be able to take full advantage of the high RPM capability and increase power throughout the entire RPM range. Especially, when paired with our JHM Stage 2 ECU and TCU Tuning Combo and our JHM 2.75" Performance Exhaust system. Want even more?
