The Hi-Flow Performance exhaust system provides a gain in horsepower combined with the right amount of aggressive tones consistent with the performance image of the MINI Cooper S. The free flowing re-usable air filter allows the engine to develop more horsepower while providing superior protection against dirt and debris, extending the engine life. Power gains expected should approach 15HP.

Our kit includes the Borla Cat Back Exhaust system and a Hi-Flow intake filter. You will not believe the difference this kit will make! This kit can easily be installed by any serious DIY'er or by a local service shop in just a few hours.

Racing expertise for more fun in everyday driving. The Mini Mania Stage 1 Kit for the MINI Cooper S includes components whose development is derived directly from expertise gained from motor racing. This version of the new Mini Mania kits thus carries on a tradition which dates back 32 years of racing success of the Classic and BMW MINI. The resulting package fires the MINI Cooper S to new performance peaks and even greater driving fun!

Choose Borla Street or Borla Sport Exhaust from the pull-down menu. Get the street version if you just want a slightly deeper tone over stock with a mild cruising sound. The 'sport' version offers a more aggressive tone with slightly more volume for those wanting a more 'sporting' sound. Both exhaust systems are 2 1/4" stainless steel system with twin 4" chrome tips.

The Borla system installs 'downstream' from the secondary catalytic converter. This requires cutting of the stock system just behind the cat, where the Borla system is attached. The rest bolts right-in. For US model MINIs only.
