Flowmaster 3in.IN(C)/2.5in.OUT(D) 4x9x18 FlowFX Muffler

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 "straight-through" stainless steel perforated core, surrounded with high temperature sound absorption materials delivering a deep 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 the both sides of the case. The Flow FX mufflers are perfect for the person looking for a quality "straight-through" performance muffler at an economical price point.
