Milltek, OPF Bypass Resonated BMW M3 M4 G82

Expert's advice:

Unlock the full potential of your BMW with the Milltek OPF-Delete Midpipes. These high-flow, non-resonated midpipes replace the restrictive factory sections and remove the OPF (gasoline particulate filters), enhancing both exhaust flow and acoustic presence.

The Milltek OPF bypass will replace the mid-pipe section of the exhaust and remove the OPF filter. Please note that this Milltek OPF bypass requires an ECU Remap.
