Description
Overview
The Flowmaster Flow FX Extreme cat-back exhaust system is engineered specifically for the 2004-2015 Nissan TITAN equipped with the 5.6-liter V8. Built to deliver serious performance gains and an aggressive tone, this exhaust system replaces the restrictive factory setup with a free-flowing, durable design that transforms how your TITAN sounds and performs. If you’ve been searching to shop for exhaust upgrades that combine proven flow with rugged reliability, this Flow FX catback exhaust delivers on both fronts.
At the heart of the kit is a Flow FX series muffler paired with 3.00-inch mandrel bent 409 stainless steel tubing. The mandrel bends preserve full pipe diameter through every curve, allowing maximum exhaust flow and long-term durability. Dyno testing showed an extra 16 horsepower and 23 lb-ft of torque at the rear wheels over stock, making this a genuine performance exhaust for your truck.
Aggressive Sound, Real Gains
The Flow FX muffler produces an aggressive to moderate sound level, giving your TITAN a bold, purposeful voice without excessive drone. The silver-finished muffler and exhaust pipe components have a 3.00-inch center inlet and center outlet, with an overall muffler length of 48.78 inches. This single tail pipe car exhaust setup is designed to breathe better than factory while maintaining a clean, functional appearance.
Built for Off-Road Clearance
This exhaust system features a turndown style, dump exit positioned right after the muffler to eliminate the over-axle tailpipe. Removing that tailpipe improves ground clearance and departure angle, which is a real advantage when you’re driving in more extreme off-road situations. It’s a smart design that supports both performance and capability.
