Milltek Sport BMW M3/M4 Non Resonated OPF/GPF Bypass Mid Section (G80/G81/G82/G83)
Description
Milltek Sport BMW M3/M4 Non-Resonated OPF/GPF Bypass Mid Section replaces the factory OPF filters to reduce back pressure and increase flow. In doing so, your G80 or G82 will see quicker throttle response and faster turbo spool. This results in improved low and mid-range torque without sacrificing top-end power. The OPF Bypass will also unlock greater tuning potential.
As this is a non-resonated Mid Section, the pipework is completely straight through for the best possible performance gains. As a consequence of this, things get quite noisy! The G80/G82's S58 engine really starts to roar when you open its airways.
Looking for a slightly quieter option, more suitable for daily driving and not annoying your neighbours? Check out the resonated (quieter) OPF/GPF Bypass Mid Section here.
Designed and manufactured in the UK!
*Please note: This OPF delete is only compatible with the factory BMW exhaust system. It DOES NOT FIT the Milltek Axle Back Exhaust System for the G80 3 and G82 M4.
