Milltek GPF/OPF Bypass - Large Bore Downpipes with OPF/GPF Bypass and Decats - F82/83 M4 Coupe/Convertible & M4 Competition Coupe (OPF/GPF models only) - 2019 - 2020 - SSXBM1128
Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to ensure ultimate without the loss of mid-range torque. All of the Milltek exhaust systems endure a comprehensive acoustic development process to deliver a tone that is sporty and crisp, without ever inducing NVH, drone or cabin resonance.
Every Milltek system is designed, developed and hand-finished here in the UK by time-served craftsmen, each one produced in aerospace grade type 304, non-magnetic stainless steel. This superior material is less susceptible to discolouration, lasts almost indefinitely and is used throughout the entire construction of our pipework, silencers and associated hardware.
The use of de-cats, sports cats are for off road/motorsport use only. Using these parts would inhibit your vehicle from passing a MOT test.
Only EC type-approved components are legal and fit for road use.
If non EC type-approved components are fitted at Awesome, the vehicle cannot be driven from our premises on the road, the vehicle will need to be recovered on a trailer to prove your intention is for off road use.
