Description
The Dinan Free Flow Axle-Back Exhaust for the MINI Cooper S F55 is engineered by Dinan to improve exhaust flow, reduce back pressure, and deliver measurable performance gains with a refined, sporty exhaust tone. Designed specifically for the 5-door MINI Cooper S platform, this system balances everyday comfort with an aggressive character when driven hard.
At cruising speeds and low RPM, the exhaust maintains a controlled, civilized sound level. Under acceleration, it produces a deeper, more engaging tone without excessive volume. As with all Dinan exhaust systems, special attention is given to minimizing low-RPM drone to ensure the cabin remains comfortable during daily driving.
The system is manufactured entirely from 16-gauge 304 stainless steel, providing long-term durability and excellent resistance to corrosion. A straight-through 2.5-inch exhaust design optimizes airflow efficiency and contributes to increased horsepower and torque. The exhaust exits through twin 90 mm black ceramic-coated stainless steel tips, laser engraved with the Dinan logo, delivering a clean, high-performance appearance that complements the MINI’s rear styling.
Installation is simple and straightforward thanks to a bolt-on design that utilizes factory mounting points. All required mounting hardware is included, and no cutting or permanent modifications are required.
One exhaust tip is non-functional by design. For this reason, Dinan offers this exhaust system exclusively with black ceramic-coated tips to prevent uneven discoloration that would occur with polished finishes over time.
