Flowmaster American Thunder Cat-Back For Nissan Titan 5.6L (04-15) (17406)

The Flowmaster American Thunder cat-back exhaust system is a high-performance exhaust upgrade designed for the 2004-2015 Nissan Titan with a 5.6L engine. Constructed with large dual 2.50-inch mandrel-bent aluminized tubing, it flows into a Scavenger Series Y-pipe featuring two D-shaped ports arranged back to back, providing a larger surface area than conventional Y-pipes. This design enhances scavenging efficiency, helping to evacuate cylinders more effectively during the exhaust stroke, which results in increased power and torque. The system also produces a deep, powerful tone outside the vehicle, complemented by a moderate interior sound. The dual tailpipes exit either out the sides behind the rear tires or straight out the back for a muscular appearance, finished with polished 3.00-inch stainless steel tips embossed with the Flowmaster logo. It utilizes factory hanger locations and includes all necessary hardware and instructions for straightforward installation.

This exhaust system is a direct bolt-on upgrade for 2004-2015 Nissan Titans equipped with a 5.6L V8 engine, making it suitable for street and towing applications. It is designed to fit seamlessly with the factory exhaust connections, providing an easy installation process with all required components included. The system is ideal for enhancing vehicle sound, improving exhaust flow, and increasing performance during daily driving or towing scenarios. Its durable construction and performance-oriented design make it a reliable choice for Nissan Titan owners seeking a deep, aggressive exhaust note and improved engine efficiency.
