What you can expect
The Milltek Secondary Catalyst Bypass for the F80 M3 replaces the factory secondary catalytic converters with high-flow stainless steel pipework. By removing these restrictive secondary cats, the system helps reduce back pressure and enhances exhaust flow. The result is a deeper, more engaging BMW M3 exhaust sound and a more responsive feel from your S55-powered M3 when combined with a Milltek Sport cat-back.
Every Milltek system undergoes thorough acoustic development to deliver a tone that is sporty and crisp. Mandrel bending ensures constant-radius bends, and enlarged bore diameters over stock are used to optimise performance while maintaining drivability. Milltek’s aerospace-grade 304 stainless steel is less susceptible to discolouration and built to last.
