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 €š¬œdrone€š¬� 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 ceramic black exhaust tips for a tasteful, high-performance look.
