Milltek Sport BMW M3/M4 Exhaust System (G80/G81/G82/G83)

Milltek Sport BMW G80 M3 G82 M4 Axle Back / Cat Back Exhaust System delivers noticeable power gains, incredible sound & aggressive looks.

As standard, the Milltek system comes as an Axle Back Exhaust System however, with the addition of an OPF/GPF Bypass Mid Section, it becomes a full Cat Back Exhaust System.

Crafted from the highest quality type-304 aircraft-grade stainless steel, this system provides a considerable weight saving over the factory exhaust. The Milltek upgrade dramatically reduces back pressure, improving throttle response with no loss of low-end torque. Mandrel bending in the pipework ensures full-flow bends for better gas flow. Milltek Sport exhaust systems are increased in bore to ensure ultimate performance.

Having a resonated OPF/GPF Bypass Mid Section is quieter and slightly more restrictive than the non-resonated option. It all depends on how loud you wish the car to be. If you would like to purchase a resonated or non-resonated OPF/GPF Bypass Mid Section on its own, we also have these available here.
