This American Thunder® Cat-Back kit is for 2004-2015 Nissan Titan pickups with the 5.6L engine and all cab/bed configurations except Crew cab/Long Bed. Manufactured using durable 409S stainless steel, the kit features flanged dual inlet pipes that run back into a 70 Series™ performance muffler exiting into a 3.00-inch mandrel-bent tailpipe. The tailpipe exits in the stock location on the passenger side of the vehicle and is finished off with large 3.50-inch diameter polished stainless steel Flowmaster® exhaust tip. As an American Thunder system, it provides improved horsepower and torque, along with a moderate performance sound level both inside and outside the truck. Instructions and all the necessary hardware are included with the kit for an easy bolt-on installation.
