Description
Overview
The Flowmaster® Flow FX® cat-back exhaust system is engineered specifically for the 2022-2026 Nissan Frontier equipped with the 3.8-liter engine. Built to unlock the sound and performance your truck deserves, this complete exhaust system replaces the restrictive factory piping with free-flowing, mandrel-bent tubing for improved exhaust gas flow. Whether you’re upgrading for a deeper tone or reaching for more usable power, this catback exhaust delivers a purposeful, custom look right out of the box.
Constructed from durable 409 stainless steel throughout, this performance exhaust is designed to stand up to years of road use and harsh conditions. The system routes through 2.50 and 3.00-inch mandrel-bent pipes, so exhaust gases move smoothly without the crimps and restrictions found in stamped factory tubing. At its heart is the Flow FX “straight-through” muffler, tuned to produce an aggressive-to-moderate sound level while maximizing performance.
Key Benefits
When you shop for exhaust upgrades that combine style, sound, and genuine power gains, this Flowmaster car exhaust checks every box. It’s built to gain up to 6 horsepower and 5 lb.-ft. of torque at the rear wheels over stock, giving your Frontier a noticeable boost in both attitude and output. The single-exit design finishes with a 4.00-inch black ceramic tip featuring the embossed Flowmaster logo for a clean, custom appearance.

The straight-through muffler design is what gives this exhaust system its character: an aggressive-to-moderate tone that comes alive under throttle without droning on the highway. The 20-inch overall length muffler features a dual inlet and a center 3.00-inch outlet, feeding a single tail pipe for a factory-plus look that still turns heads. If you’ve been searching for an exhaust exhaust pipe setup that balances daily-driver manners with real character, this is it.
