Description
The Flowmaster American Thunder Cat-Back Exhaust System is engineered for 2004–2015 Nissan Titan trucks equipped with the 5.6L engine, delivering moderate exhaust sound with improved power and torque. Designed to bolt directly to the factory catalytic pipes, this system utilizes mandrel-bent 16-gauge aluminized steel tubing for maximum flow and durability.
Featuring a Scavenger Series Y-pipe, the system enhances cylinder scavenging and delivers a stronger exhaust signal than conventional Y-pipes, increasing horsepower and torque. Exhaust gases then flow into the 70 Series Big Block II chambered performance muffler, producing a deep, powerful tone outside the vehicle while maintaining a moderate sound inside the cab.
The dual tailpipes can exit either behind the rear tires for towing or straight out the back under the bumper for a muscular appearance. Each tailpipe is finished with a 3.00-inch polished stainless steel tip embossed with the Flowmaster name. The system installs using factory hanger locations and connections, and includes all necessary hardware and detailed instructions for an easy installation.
