Overview:
Flowmaster’s Flow FX series mufflers deliver a moderate performance tone for the enthusiast looking for an exhaust note that is different from the “chambered” muffler sound. The interior features a large 3.50-inch “straight-through” stainless steel perforated core, surrounded with high-temperature sound absorption materials delivering a deep traditional mellow tone. The internal flow design is reversible, so the muffler can be installed in either direction to best suit the vehicle application and offsets needed. Features include fully MIG-welded “bright” 409 stainless steel construction with the Flow FX logo embossed on both sides of the case. The Flow FX line of mufflers are perfect for the person looking for a show quality performance muffler at an economical price point and in a compact sized case.
