Flowmaster's FlowFX series mufflers deliver a moderate performance tone for the enthusiast looking for an exhaust note that is different from the "chambered" muffler sound. With a 3.0-inch inlet and outlet size and a 6-inch diameter body, this muffler is a great choice for large displacement gas engines. The interior features a large 3.0-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. Features include fully MIG-welded "bright" 409 stainless steel construction with the FlowFX logo embossed on both sides of the case. The FlowFX 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.
