Dinan engineers designed the F55 MINI Cooper S 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. Like all Dinan exhausts, our F55 Free Flow Exhaust is engineered to combat low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. 

The aggressiveness of a track exhaust and the refinement expected of a daily driver, all wrapped into one, is what many desire: but they find hard to acquire. This 'white whale' of a product just became easier to locate with Dinan's Free Flow exhaust system that utilizes the factory exhaust valve in concert with Dinan's muffler design to allow for this Jekyll and Hyde ability.

Dinan's Free Flow exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. Dyno tuned for maximum exhaust flow with minimum back pressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle. This is accomplished thanks to a computer controlled valve that limits noise during low speed driving and opens fully during high-load conditions to allow free flow. For maximum enjoyment and sound when the valve is opened on the M2 exhaust the system becomes a straight pipe to achieve peak power, flow and tone. No matter if the valve is open or closed the exhaust gasses make their exit via Dinan's signature enlarged, laser engraved, black ceramic quad tips. Not only will your M2 sound breathtaking, it will look the part as well.

This system is built with ease in mind and utilizes a simple bolt-on installation with included mounting hardware. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 90 mm ceramic black and laser engraved exhaust tips for a tasteful, high-performance look that yields a maximum performance gain of 4 horsepower and 4 ft-lbs of torque.
