Description
Overview
The Flowmaster Flow FX Muffler is a straight-through performance muffler engineered for the enthusiast who wants a distinctive exhaust note that stands apart from the traditional “chambered” Flowmaster sound. As part of the Flow FX series, this exhaust muffler delivers a moderate performance tone with a deep, traditional, mellow character that suits late model muscle car builds without overwhelming the cabin. If you’re searching for a Flowmaster muffler that blends attitude with everyday drivability, the Flow FX line hits that mark.
Inside, the Flow FX uses a large 3.00-inch straight-through stainless steel perforated core surrounded by high-temperature sound absorption material. This design promotes strong flow while the packing tames harshness, producing that signature deep, mellow tone. Because the internal flow design is reversible, the muffler can be installed in either direction to best suit your vehicle application and the offsets your build requires.
Show-Quality Construction
Every Flow FX muffler is fully MIG-welded from “bright” 409 stainless steel for a clean, durable finish, and carries the Flow FX logo embossed on both sides of the case. The compact case size makes it easier to fit into tight chassis routing, while the polished stainless look means it’s ready to be seen. This is a show quality performance muffler offered at an economical price point, making it an easy upgrade for anyone building out a flowmaster exhaust system.
