Dinan Free Flow Axle-Back Exhaust for BMW | F30 | F32 | 335i/435i
Dinan engineers designed the F30 / F32 BMW exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Dinan also incorporates a Helmholtz chamber design that reduces resonance or "drone" at low RPM.
The system is built to exacting specifications to ensure perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm polished stainless steel exhaust tips for a tasteful, high-performance look.
Note: Factory computer-controlled exhaust valve is eliminated. Does NOT fit F33 435i Convertible

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
