The Flowmaster® FlowFX® Cat-Back Exhaust System is designed for 2017–2024 Nissan Titan trucks with the 5.6-liter engine and short wheelbase (139.8-inch). Constructed entirely from durable 409 stainless steel, this system features 3.00-inch inlet tubing flowing into dual 2.50-inch mandrel-bent pipes for improved exhaust gas flow. The FlowFX “straight-through” muffler delivers an aggressive-to-moderate sound while providing maximum performance, with dyno-tested gains of +11 hp and +13 lb-ft at the rear wheels.

Exiting on the same side in front of the passenger rear wheel, the system includes dual 4.00-inch black ceramic-coated tips for a custom, high-performance look. Designed for easy installation using factory hanger locations, the kit comes complete with all necessary hardware and instructions. Backed by Flowmaster’s Lifetime Limited Warranty, this system is perfect for Titan owners seeking both style and performance.
