Milltek Non-Resonated Cat-Back Exhaust - BMW 4 Series F32 - Polished Tips - SSXBM1005

Milltek Non-Resonated Cat-Back Exhaust System for BMW 4 Series F32 428i and 435i models. Direct factory fitment using OEM hangers; no modification required. This is a cat-back system only-connects directly to the existing factory downpipe and catalytic converter.

Engineered T304L stainless steel construction with mandrel-bent piping and hand-finished polished trims. The non-resonated design eliminates the factory resonance chamber, delivering a fuller, more aggressive tone under throttle while maintaining OE-quality fitment and durability through all conditions.
