American Thunder Cat-Back Exhaust System 2004-2008 for Nissan Titan 5.6L V8 (Exc. Crew Cab) 2.5" Tubing 3" Polished SS Tip Dual Rear/Side Exit 70 Series Big Block Muffler Aluminized Steel
FLOWMASTER MUFFLERS 17406 Features:
Introducing the American Thunder cat-back exhaust system for the 2004-2015 Nissan Titan with 5.6L engine. This performance exhaust system bolts up to the factory cat pipes with large dual 2.50-inch mandrel-bent aluminized tubing flowing into a Scavenger Series Y-pipe that creates a stronger signal than conventional y-pipes by using two D-shaped ports back to back, giving a larger surface area than just two round pipes joined together. This creates a much stronger scavenging effect to help evacuate the cylinders during the exhaust stroke netting more power, torque and a deep unique tone. The added torque is especially useful when towing. The system flows out of the Scavenger Y-collector into a 70 Series Big Block II performance muffler giving a deep powerful sound outside the vehicle, with a moderate tone inside the cab. The mandrel-bent tailpipes exit either out the sides behind the rear tires, which is ideal for towing or straight out the back under the rear bumper for a muscular look. The dual tailpipes are finished off with a pair of 3.00-inch polished stainless steel tips embossed with the Flowmaster name. The system utilizes the factory hanger locations and connections and includes all necessary parts, hardware and detailed instructions for an easy at home installation.- Includes Hangers and Hardware for an Easy Installation
