This Borla Cat-Back system is a simple slip on system for all 2011 and newer (R60) MINI Cooper Countryman S turbocharged models. 100% stainless steel inside and out. Twin round tips fill out the rear valence perfectly with no rubbing. Not too loud, not too quiet. Specifically engineered for turbo applications that require greater flow capacity than naturally aspirated applications. The increased flow characteristics of this MINI Cooper Countryman S exhaust offer a gain in boost response, a broader powerband and increases overall peak horsepower. It also offers a weight savings over the bulky, heavy stock exhaust system.
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.
