The lower priced sibling of our renowned Touring Edition Exhaust, the Track Edition is made of the same quality T304L stainless, is crafted in house, and delivers the same power gains. The difference comes in the removal of AWEs sound cancelling 180 Technology rear mufflers, which can be found on our Touring Edition Exhaust. Warning this thing gets rowdy! This system will produce a louder tone in the mid range. S Tronic owners beware: This system will be especially loud at part throttle. Given the removal of the rear mufflers, this system cannot be returned due to sound. As far as downpipes (sold separately), AWE offers Resonated and Non Resonated Downpipes.
