The muffler and the pipes are made from high-quality 409 stainless steel which means you won’t have to worry about rust or other types of corrosion. The kit will surely serve you the lifetime of your truck. The kit is designed as a direct replacement for a factory-installed muffler with all the necessary hardware included. The pipes are mandrel bent, which minimizes restrictions to the gasses flow thus increasing the useful power of the engine. Maximum gains in horsepower and torque are 9 hp and 11 lb. ft. of torque respectively.
Besides power gains, the muffler offers an aggressive loud exhaust sound that you can make truly monstrous by pushing a button on a wireless remote. This FlowFX Active Dual-mode muffler features new W.A.V.E. Technology™ (Wireless Active Valve Exhaust™). It works perfectly thanks to a high-quality wireless controlled actuator valve on the Power Chamber® redirecting exhaust through the straight dump pipe. Once you activate this mode, you’ll surely let everyone know who is the boss on the road. When needed, you simply turn it back, achieving a relatively mild performance exhaust tone.
