Stainless Performance System with Black 89 mm Tailpipes for BMW 4 Series 435i F33 Cabriolet and F36 Gran Coupé
Transform the character of your 4 Series with a premium stainless rear system engineered for flow, tone and longevity. This Dinan unit frees up the factory system, reducing restriction and unlocking a richer, deeper soundtrack that stays calm on the motorway yet comes alive under throttle. Ideal for daily use, spirited B-road drives and weekend detailing pride, it looks as good as it sounds thanks to stealthy ceramic-coated twin outlets.
A tuned resonator chamber dramatically cuts low-frequency boom, so you enjoy the performance note without the cabin drone that often plagues lesser systems. Built from robust 16 gauge 304-grade stainless, it resists corrosion in UK weather and mounts to the original hangers for a precise, bolt-on fit.
- Specifically tailored for 2014 to 2016 BMW 4 Series 435i F33 Convertible and F36 Gran Coupé
- Free-flowing design enhances response and delivers a purposeful, sporty tone
- Noise-cancelling chamber helps remove low rpm resonance for comfortable cruising
- 100% 16 gauge 304 stainless construction for long-term durability
- Twin 89 mm ceramic black tailpipes for a subtle, OEM plus finish
- Direct bolt-on using factory mounting points for straightforward installation
- Refined at light load, assertive when you open it up
