The Borla exhaust for the MINI (non S) is a true cat-back performance system. This exhaust will give the Cooper a deeper and throatier voice that sets it apart from the stock Cooper and even the Cooper S version. This exhaust bolts to the stock catalytic converter and includes a resonator and rear muffler to get a more aggressive sound without being overly loud and intrusive. And we measured an 8 horsepower gain at the wheels on our dyno! This exhaust will re-awaken your MINI and put a bit more pep in your driving.

Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out. Borla guarantees every muffler with a 1,000,000 mile warranty.
