The Borla Aggressive Catback Exhaust for the Mini Cooper S. It seems logical that the age-old axiom ‘great things come in small packages’ was imported to America from Europe. Few vehicles have ever lived up to that byline better than the R53 Mini Cooper S. Complimenting the supercharged motor with a free breathing, mandrel-bent Borla cat-back system gives the Cooper S even more attitude.
Borla uses mandrel bent T-304 stainless steel tubing and free flowing mufflers to give the 02-06 Mini Cooper S a little more bite, and just enough bark. Borla is famous for their Million-Mile Warranty, and the R53 Cooper S cat back systems get the same warranty. Borla offers two different cat backs for the R53 Mini Cooper S. The Aggressive, and the Standard. Both yield improvements in power, but they differ in sound and looks.
The Aggressive exhaust uses less restrictive mufflers and straighter piping to allow for a more aggressive sound and increased power in your Cooper S.
