Milltek SSXBM1003 BMW 428i F32 Coupe Performance Rear System - Twin Exit Black Tips

Unlock the sound and character your 4 Series deserves with this Milltek Sport rear system designed for the BMW 428i F32. Expect a sharper, sportier tone and an engaging drive thanks to a straight-through, non resonated centre section that prioritises flow and excitement while keeping cabin boom in check. The factory-style dual exit with stealthy black ceramic-finished tips delivers a premium, OEM-plus look that suits the 2.0 turbo petrol perfectly.

Engineered and built in Britain from T304 grade austenitic stainless, this system uses constant-radius, mandrel-formed tubing for smooth gas speed and crisp throttle response. Precision jig manufacturing ensures a direct bolt-on fit to the original mounting points, with excellent durability for year-round UK road use.
