Description
Overview
The Flowmaster Flow FX Muffler brings show-quality sound and construction to enthusiasts who want a performance muffler that stands apart from the traditional “chambered” note. Engineered as part of Flowmaster’s Flow FX series, this exhaust muffler delivers a moderate performance tone that is deep, traditional, and mellow — an ideal upgrade for anyone chasing a refined yet aggressive exhaust note without excessive drone.
Inside the compact case, a “straight-through” stainless steel perforated core is surrounded by high-temperature sound absorption materials. This design produces the smooth, deep tone Flowmaster mufflers are known for while keeping the muffler efficient and durable. If you want a flow master exhaust upgrade that looks as good as it sounds, the embossed Flow FX logo on both sides of the case adds a finished, premium appearance under the vehicle.
