Unsurpassed Quality, Fitment, Performance and Sound…Made in Arizona. When we set out to build the finest exhaust system for the McLaren 650S/MP4 we had a monumental task in order to create something better than what developed was developed in Woking, England. We wanted a more aggressive supercar sound without being obnoxious. With twin turbo power, sound is only half of the agenda, maximizing the power increase and helping the turbos perform optimally.
