Built for the Supercharged Mini Cooper S (R50 & R53) models, this professionally bent, exquisite exhaust system is proven to optimise performance and flow output while significantly improving both the sound and power by comparison to the Mini Cooper's original equipment. The exhaust is a fantastic design that has been sold at a far higher price by brand leaders. Pro-silencers, the tube diameter is 2.5 inches, dropping to 1.75 inches post-silencer. The tailpipe diameter is 3 inch. Unlike many cheaper systems on the market, this exhaust fits perfectly and has an excellent sound- not loud and unpleasant to drive like many aftermarket systems. Fits 2000 to 2008.
