Performance Rear System for BMW 4 Series F32 428i 2.0 Turbo, Twin Exit 435 Look, Resonated, Black Ceramic Tailpipes - SSXBM1007

Give your F32 428i a purposeful twin exit rear end and a refined, deeper soundtrack with this UK-built Milltek rear section package. Designed for the 2.0 turbo N20 petrol coupe, it replaces the factory rear pipework from the catalyst back with free flowing, mandrel bent T304 stainless steel and a resonated centre to keep motorway manners in check while delivering a sporty tone when you lean on it. The stealthy black ceramic coated tailpipes complete the OEM plus finish with long lasting heat resistance and corrosion protection.

We run Milltek systems on our own builds and our customers love the fit, finish and everyday usability. If you want a high quality 428i upgrade that looks factory fresh, sounds right and is engineered to last, this is the one we recommend.

Materials and engineering

Crafted in the UK from type 304 stainless steel throughout, with carefully developed silencer design and tube geometry. The resonated layout controls unwanted frequencies for long distance comfort while freeing up flow compared to the stock system. The result is a deeper, more characterful note under load without intrusive drone inside the cabin.

Fitting

Professional installation recommended. Once the correct 435i M Sport lower trim is in place, this is a straightforward bolt-on from the catalyst rearwards. For installation, speak to MJ Modifications in Warwickshire. Request a fitting quote at info@mjmodifications.co.uk.
