The ALTA Performance R53 exhaust system sounds, looks great and performs the way the factory system should have. The exhaust note is pleasant and lively at idle while giving a sporty, throaty growl under hard acceleration. You get all these benefits without any annoying resonances at high idle or while cruising the interstate! 

Construction

The ALTA cat-back exhaust uses 2.5" diameter 304 Stainless Steel tubing and is the perfect match for the high revving, supercharged power plant in your Cooper S. The ALTA Performance exhaust system directs exhaust gases through two strategically placed mufflers. This combination reduces the sound volume down to a low growl while the straight through design provides maximum air flow. While perfectly suited for otherwise stock Cooper S's, the system is a real power builder on Cooper "S" equipped with our S/C pulley, intake system and other engine modifications.

Single Side Design

The "S" shape of the ALTA exhaust system favors high horsepower by increasing exhaust gas velocity, while maintaining the factory exhaust tip location. Our exhaust system travels down the center of the car, around one side of the battery box, then out the center bumper cut out. This routing is simple, light weight, and very clean looking. Our system is offset to the passenger side of the car, to help counterbalance the weight of the driver.

V-Band
