Milltek Cat-back Exhaust | OE-style Twin-Outlet | Non-resonated Louder | Cerakote Black Tips | BMW F32 428i Coupe | N20 Engine Only | Manual | 2014 to 2020 | Part No: SSXBM1003
Transform your BMW 4 Series with the Milltek cat-back exhaust for the F32 428i N20. This non-resonated system delivers a crisper, louder, more engaging exhaust note while maintaining refinement with minimal drone. The OE-style twin-outlet layout and Cerakote Black tailpipes give a stealth, factory-plus look that suits the 428i perfectly.
Every Milltek system is designed, developed and hand-finished in the UK by time-served craftsmen. Constructed from aerospace grade type 304, non-magnetic stainless steel, it is highly resistant to discolouration and built to last. Mandrel bending ensures constant radius bends for optimised gas flow, and carefully enlarged bore diameters unlock performance without sacrificing mid-range torque. Milltek’s comprehensive acoustic development delivers a sporty, crisp tone without inducing NVH, drone or cabin resonance.
