Description

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. Fitment Notes: • Direct fit: BMW 4 Series F32 428i and 435i • Requires 435i M Sport rear valance (available separately from BMW dealer) • Cat-back configuration-does not include downpipe or catalytic converter modifications • Uses factory suspension and mounting points Every system is dyno-tested and designed for both street and track use. Designed and manufactured in the UK with 40+ years of performance exhaust heritage. Tested at the Nurburgring.
