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 2002-2006 R53 Mini Cooper S. The Aggressive, and the Standard. Both yield improvements in power, but they differ in sound and looks.
This system features more baffled mufflers and tighter bends for a quieter 02-06 Cooper S catback that frees up power with less resonance than the aggressive system.
