AWE SwitchPath Cat-Back Exhaust (Silver 102mm Tips) - F8X M3 M4

Bimmerworld View: The AWE SwitchPath exhaust uses factory style control valves to change between a sporty street mode and a more aggressive track mode. This is the best of both worlds for enthusiasts who use the car for commuting as well as sport driving.

This AWE Tuning SwitchPath axle-back exhaust system is designed to fit BMW F80 M3 Sedan and F82 M4 Coupe models. This free-flow cat-back exhaust is a simple cut-and-clamp installation behind the factory catalytic converters, replacing the center muffler with an x-pipe. The muffler section has internal valves that allow you to choose a sporty but reserved exhaust note, or open the valves for a more rowdy sound. Your factory valve actuators will be reused, and the valves will operate just like stock. Constructed of T304 stainless-steel, this version features quad 102mm chrome silver tips that fit perfectly in the stock rear bumper openings.
