Varex™ mufflers use patented technology to combine both the design of the stock muffler and the performance muffler into one single compact unit. A sophisticated butterfly valve mechanism is implemented to redirect the exhaust gas flow and vary between the two. For higher sound level, the exhaust flows are directed through the opening path and produce maximum power with a robust sound level (or the “sports car note”) and near-zero resistance. 6″x 10″x 16″ Body 3″ inlet with 2 bolt flange Single pipe outlet Side mounted motor Made from 304 Stainless Steel in matt finish Allow 2 inch clearance for actuating motor
