Looking to maximize the magnificent roar of your S58? Look no further than the AWE Track Edition exhaust system, engineered for maximum sound and flow! Featuring a precision x-pipe and quality 3" US-sourced stainless steel construction, this exhaust boasts rich and rowdy tones for the true performance enthusiast. Unlike its SwitchPath sibling, the Track Edition exhaust does not incorporate a muffler for an unrestrained roar. Combined with a hefty 13 lbs of weight savings, this system does more than improve flow.
