SSXBM1008 - Catback System for BMW F32 428i 2.0T Auto - Dual Exit, Resonated, Polished Tailpipes

Transform your BMW 4 Series driving experience with this Milltek catback system for the F32 428i 2.0 turbo. Expect a clean, sophisticated soundtrack on the motorway and a sharper, sportier note when you lean on the throttle. The dual exit rear with mirror-polished tailpipes keeps the factory look while adding a premium finish. If you want a high-quality stainless system that feels refined day to day and comes alive on B-roads, this is the upgrade.

Engineered and hand-finished in Britain from high-grade type 304 stainless steel, the pipework uses precision mandrel bends for consistent internal diameter and smooth gas flow. The resonated layout helps keep cabin boom in check for comfortable cruising, while still delivering a purposeful tone under load. Fitment has been excellent on our own builds and for customers, with consistent feedback on the sound quality, craftsmanship and alignment.
