DNN Axleback Exhaust Systems

NOTE: The exhaust system is only offered with tips as one of the tips is non-functional and would lead to non-matching discoloration over time if polished tips were used. The 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 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. 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 Axle-Back 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.
