Milltek Resonated Cat-Back Exhaust - BMW 4 Series F32 428i Auto - 435i-Style Dual Outlet - Polished Tips - SSXBM1012

Direct-fit resonated cat-back exhaust system for BMW 4 Series F32 (428i, 435i). Hand-finished T304L stainless steel construction with polished tips. This system replaces the original exhaust from the catalytic converter back, reducing volume while adding engineered tone character without aggressive resonance. Uses OEM hangers and suspension points-no modification required.

Mandrel-bent T304L stainless steel throughout ensures durability in all weather conditions. The resonated design targets the OEM resonance point to eliminate drone during highway cruising while maintaining a refined exhaust note at full throttle. Decibel-tested for street compatibility.

Fitment Note: Requires BMW 435i M Sport rear valance (available through your BMW dealer) for proper fitment and visual alignment with the M Sport diffuser design.

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