As a result of stringent testing, we have engineered our systems with the correct pipe diameter and layout to extract maximum horsepower from your engine. Only the finest stainless materials are used in the construction of our exhaust systems, in addition to the use of extremely lightweight titanium for select models. Our exhaust systems are also finished with shotpeened end tips for a subtle appeal unlike any other system currently available.
