Description
Overview
Upgrade your 2022-2026 Nissan Frontier equipped with the 3.8-liter V6 with the Flowmaster® American Thunder® cat-back exhaust system. Engineered as a complete bolt-on kit, this performance exhaust replaces the restrictive factory setup with 2.50 and 3.00-inch mandrel-bent pipes that promote smoother, less turbulent exhaust gas flow. If you’ve been comparing a Borla exhaust, Corsa exhaust, or MagnaFlow exhaust for your truck, this Flowmaster catback exhaust delivers a proven combination of sound, style, and measurable power for the Frontier platform.
Built for durability, every pipe and component is constructed from 409 stainless steel, so this car exhaust upgrade is engineered to stand up to the road for the long haul. The system centers on a Super 50 series muffler with dual inlets, a center 3.00-inch outlet, and a 23.14-inch overall length, tuned to produce an aggressive-to-moderate sound level that comes alive under throttle without droning on the highway.
Performance and Sound
Dyno-backed gains of up to 8 horsepower and 7 lb-ft of torque at the rear wheels over stock make this more than just a great-sounding exhaust system. The Super 50 muffler is designed to maximize performance while delivering the deep, aggressive tone Flowmaster is known for. It’s a serious performance exhaust that lets your Frontier breathe and pull harder.
Style and Fitment
This single-exit system finishes with a 4.00-inch polished stainless steel tip featuring the Flowmaster logo embossed for a custom, factory-plus look. The silver pipe finish and black muffler give the underbody a clean, purposeful appearance. Because the system uses all existing factory hanger locations, installation is straightforward — no cutting or custom fabrication required. Every kit includes installation instructions and all necessary hardware, making this an achievable at-home project.
