AWE has merged decades in supercar performance products with rigorous study of the peerless engineering behind the McLaren MP4-12C to create one of the finest exhaust systems available, for one of the finest vehicles available. The AWE Performance Exhaust for the McLaren MP4-12C is designed to perfectly smooth the aggressively raw tone that results from mating the AWE Performance Catalysts to the stock exhaust system. The resulting acoustic character is nothing short of breathtaking, offering a note that is both hard-hitting and exotic.The exhaust is constructed from mandrel bent 304 stainless steel at 3" diameter throughout and features a small balance opening between the banks which produces the exotic, high pitched wail. The AWE Performance Exhaust features logo tips evoking the factory geometry in a high profile bare stainless steel machined finish.

The AWE No Check Engine Light Guarantee offers peace of mind against the appearance of Check Engine Lights when products are installed properly and used as intended, on vehicles with no additional modifications (with the exception of other AWE products intended to work with the product in question). No problems, no lights. Easy.
