This cat-back exhaust system incorporates factory style NPP dual mode exhaust valves which use the factory exhaust valve motors (not included). The valves help regulate, direct and control the flow of exhaust gases by opening, closing, or partially obstructing passageways depending on throttle position for maximum performance. Dual free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. The performance cat-back exhaust system is constructed of 3" mandrel-bent, 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking..
