Milltek Midpipe GPF/OPF Bypass, BMW M5 G90/G99

Expert's advice:

Unlock the full potential of your BMW G90 M5 or G99 M5 Touring with the Milltek Sport OPF-Delete Exhaust 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 for the BMW M5 G90 & G99 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.
