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. This will affect your vehicle's performance and can even lead to engine damage if the catalyst completely clogs. 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? Check out our JHM Lightweight DSG Flywheel for even faster acceleration capabilities.

Please Note: You will need to send in your car's stock header cores to be upgraded to the JHM spec. Turnaround is 2-3 weeks (Not including international transit time).
