R53 Cat-Back Exhaust System

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! Read more below!

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

ALTA exhaust systems are the only systems available for the MINI which feature V-band flanged joints, V-band flanges make installation easy because they do not require a gasket and offer more system adjustment for better tip placement. Easy to remove and reinstall for routine maintenance, and never any blown gaskets!

Finish Options

This ALTA exhaust system features a brushed metal finish. The muffler section is available in either a brushed metal or Stealth Black option. The brushed finish has a grainy metal look which is easy maintained with a Scotchbrite abrasive pad. The Black allows you to hide your aftermarket exhaust for a stealth look.

Proven Horse Power


Cooper S Catback Test on stock MCS

The above test was done on our R53 with only the ALTA 15% Supercharger pulley installed. This shows the HP and TQ gains from installing the ALTA 2.5" Catback exhaust. As you can see you gain 10WHP and 20-10 Ft-lbs of TQ. Later on we did a test on our JCW testing the JCW exhaust against ours and our exhaust made an addition 3WHP over the more expensive JCW exhaust!


Stage 3 Dyno Run

The above test was done on our R53 with our 15% SC pull and an ALTA cold air intake installed. Adding the catback to this car shows additional gains over the other test. You can see you gain 8WHP and 8-5 Ft-lbs of TQ.
