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. Turner Motorsport has been the leading Borla dealer for BMW exhausts since we sold our first system in 1996, including using Borla Exhausts on every Turner BMW racecar.

This Borla Exhaust fits the following MINI models:
2002-2007 R50 MINI MINI Cooper
2005-2008 R52 MINI MINI Cooper Convertible

The Borla Race exhaust is uses smaller mufflers to create a very aggressive, loud, and fun sound. The Race is intended for people who want their MINI to bark and not be inconspicuous. Where the Borla Street exhaust is great for people who want to hear the engine a tiny bit more, the Race is an exhaust that you will hear all the time. It pops and burbles with every lift off the gas and creates a throaty rumble as you rev through the RPM band. It's a very un-MINI like sound that actually works well with the MINI's motorsport and sporting heritage. It installs on to the factory cat section with all of the factory gaskets and hangers.

Every Borla is made with 304 stainless steel for the internals and muffler body.

Borla makes a Street and Race version of this exhaust with the Street being a noticeable but moderate sound easily tolerated for daily driver use. The Street (Touring) exhaust is perfect for someone who wants to hear a bit more of the engine without waking up the neighborhood or annoying the car next to you in traffic. It suits the character of the Cooper S very well. Borla builds this exhaust as a full cat-back system with dual rear mufflers. It's also about 10lbs lighter than the stock original system.
