Dinan - Free Flow Stainless Exhaust - BMW F22 M235i



Dinan® engineers designed the F22 BMW M235i 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 exhaust tips for a tasteful, high-performance look.

- Maximum performance gains are 6 horsepower  @ 6600 RPM, and 5 ft-lbs of torque.
