The most important reason to buy a catback exhaust is to make more power. The ALTA exhaust has solid gains of 10 Wheel HP and 10 ft-lbs of torque. While 10 WHP is very noticeable, more noticeable is that the turbo spools roughly 200RPM sooner. This quicker spool means more low end power! It is very important to ALTA and everyone to prove the exhaust makes power, but sound level & tone should also be a concern. This system is designed to have a very mellow and pleasing note while not producing loud sounds that wakes up neighbors.
ALTA exhaust systems are made entirely of 304 stainless steel, inside and out. 304SS provides high corrosion resistance, and is excellent for extreme heat up to 1800 degrees. Other manufactures and OEMs, will use cheaper 409 stainless steel which will rust and corrode over time but the added expense of 304 stainless steel is well worth the beautiful and long lasting high polish, and durability.
Dont be fooled that 2.5" exhaust systems are big enough for your high performance Mini Cooper S. ALTA has proven time and time again 3" makes more power while keeping exhaust tones under control. Their huge 3" exhaust only weighs 1lb more than the stock 2.3" exhaust, so you dont sacrifice anything going to the ALTA 3" exhaust!
ALTA Performance mufflers have a true 3" internal diameter for uninterrupted exhaust flow. ALTA mufflers and flange connections are 3" throughout the entire length, not necked down for ultra smooth transitions throughout the system. Twin oversized slash cut exhaust tips keep that OEM styling while adding an agressive look at the same time. The tips are a high polished, dual wall construction to add a more refined look and to ensure the tips do not dis-color with extreme heat.
