MINI Cooper S 2004-2006 100% stainless cat-back system bolts to the stock exhaust after the catalytic converter. Twin round tips fill out the rear valence perfectly with no rubbing. Louder than the Borla Street #140027. This kit uses smaller mufflers and a resonator for a more agressive sound. Stock system weighed in at 45.5 LBS, the Borla weighs 33.5 LBS. We  Dyno tested many different exhaust sytems currently on the market for the Cooper S. The Borla came out on top!  Dyno results showed a peak gain of 6-7 HP power at 6250 RPM, but power increases from 3700 RPM to redline.
