Description
Overview
The Flowmaster Flow FX Muffler brings a moderate, refined performance tone to trucks and SUVs running large displacement gas engines. Engineered for the enthusiast who wants an exhaust note that stands apart from the traditional “chambered” Flowmaster sound, this Flow FX muffler delivers a deep, mellow character without overwhelming your cabin. If you’ve been searching for a car muffler that balances attitude with everyday drivability, this performance muffler hits the mark.
Inside the case, the Flow FX uses a large 3.00-inch “straight-through” X-pipe style stainless steel perforated core, wrapped in high-temperature sound absorption materials. That straight-through design keeps flow strong while the acoustic packing tunes the output to a traditional, mellow tone. The internal flow design is fully reversible, so the muffler can be installed in either direction to best suit your vehicle application and routing.

As part of the respected Flowmaster exhaust family, this exhaust muffler is built to look as good as it performs.

The compact case size makes it easy to fit into tight chassis space, and the economical price point puts genuine Flowmaster mufflers within reach.
