With the popularity of the Clubman S Alta has decided to produce a special catback exhaust designed specifically for its unique dual outlet. Just like all ALTA exhaust systems it's made out of 304SS for its polished beauty and durability. Starting out with a 3" I.D. at the cat pipe connection then "Y"-ing into two 2.25" pipes through the polished mufflers and shot out through angled, twin wall, 4" polished tips.

In our initial testing, of our Catback exhaust, we found great solid gains of10 Wheel HP and 10 ft-lbs of torque. While 10 WHP is very noticeable,the most noticeable thing you will find is that the turbo spools quicker providing roughly 200RPM quicker spool. This quicker spool means more low end power! Something you might not notice is sound. It is very important to us and everyone to make the exhaust make power, but noise/tone is the next thing people are concerned with. Our new 3"system is designed to be very very mellow and appease all types of customers. No loud "farty" Honda sounds here!

Here is the dyno test on our R56 with just the catback installed between runs. 7 runs before and after were done to ensure the gains were legit. Priced individually
