Overview
The Flowmaster Flow FX series muffler is built for the performance enthusiast who wants an exhaust note that stands apart from the traditional “chambered” sound. Engineered to deliver a moderate performance tone, this Flowmaster muffler produces a deep, traditional mellow character that adds presence to your car exhaust without overwhelming the cabin. Whether you’re upgrading a daily driver or completing a full performance exhaust build, the Flow FX brings show-quality looks and proven Flowmaster engineering to your exhaust system.
At the heart of this muffler is a large 2.50-inch “straight-through” stainless steel perforated core, wrapped in high-temperature sound absorption materials. This straight-through design promotes efficient flow while the acoustic packing tunes the exhaust note into that signature deep, 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 the offsets you need.
