Description
Overview
The Flowmaster Flow FX Muffler brings show-quality style and a moderate performance tone to trucks and SUVs looking for something different from the traditional “chambered” muffler sound. Engineered as a compact, economical performance muffler, this Flow FX series unit delivers a deep, traditional, mellow exhaust note that stands apart while keeping cabin drone in check. If you want a Flowmaster muffler that looks as good as it sounds, the Flow FX line is built to impress.
Straight-Through Performance Design
At the heart of this Flowmaster exhaust upgrade is a large 3.50-inch straight-through stainless steel perforated core, surrounded by high-temperature sound absorption materials. This design produces the deep, mellow tone that enthusiasts want from a genuine flow master exhaust component. The internal flow design is fully reversible, so the muffler can be installed in either direction to best match your vehicle application and the offsets you need — a practical touch that makes fitment easier during any exhaust muffler car install.
Built to Last and Look Good
Construction is fully MIG-welded “bright” 409 stainless steel, with the Flow FX logo embossed on both sides of the case. That combination of durable stainless steel and clean styling makes this one of the more attractive performance mufflers you can bolt into a system, all at an economical price point and in a compact-sized case that’s easy to package under a truck or SUV.
