Turn up the drama on your 2021-on John Cooper Works F56 LCI2 with this 3 inch non-resonated cat-back system. Built by Cobra Sport, the Venom configuration deletes the rear silencer for a raw, motorsport-inspired soundtrack and a seriously aggressive tone. Expect punchy crackles on overrun, sharper character at wide-open throttle and a deeper note across the rev range. This is the loud option for enthusiasts who want maximum theatre from their JCW.
Crafted in 76.2 mm pipework, this performance system runs from the post-catalyst section rearwards. It replaces the factory GPF/PPF/OPF particulate filter along with the mid and tail sections to unlock a freer-breathing exhaust path and a dramatic sound upgrade.
