Milltek Non-Resonated Cat-Back Exhaust - BMW 4 Series F32 428i Auto - 435i-Style Dual Outlet - Cerakote Black Tips - SSXBM1014

Milltek Non-Resonated Cat-Back Exhaust System for BMW 4 Series F32 (428i Auto and 435i models). This is a direct factory replacement offering increased volume and aggressive tone character compared to the original system, hand-finished T304L stainless steel construction with Cerakote Black polished trims. Mandrel-bent piping and precision CNC-formed components ensure OEM+ fitment with no modifications required.

All systems use OEM hangers and bolt directly to existing mounting points. The non-resonated design eliminates internal chambers for maximum sound character at full throttle while maintaining composure at part load. T304L stainless steel resists corrosion through any climate. Requires 435i M Sport rear valance from BMW dealer for proper fitment with this system.

Every system is dyno-tested and fine-tuned at our development center before shipment.

Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
