      Description

      Performance Muffler Solution. The Flowmaster Flow FX Center/Center Muffler with 3.50-inch inlet and 3.50-inch outlet delivers a moderate exhaust tone ideal for enthusiasts wanting a sound distinct from typical chambered mufflers. This muffler enhances exhaust flow while producing a deep, mellow tone suitable for street and strip applications, blending performance with effective sound control.

      Construction and Appearance. Crafted from fully MIG-welded bright 409 stainless steel for durability and corrosion resistance, this muffler features a natural finish with the Flow FX logo embossed on both sides. It includes a large 3.50-inch perforated stainless steel core surrounded by high-temperature sound absorption material, balancing sound attenuation with exhaust flow efficiency.

      Installation. The muffler is designed with slip-fit inlet and outlet connections suitable for clamp-on or weld-on installation. While installation is generally straightforward with no drilling typically required, some modifications or adaptation may be necessary depending on the specific vehicle setup. No hangers or heat shields are included.

      Warranty. A warranty is provided to ensure peace of mind—details available upon request.

      Application. This muffler fits universal applications; however, some adaptation may be required to accommodate specific vehicle configurations or custom exhaust systems. It is designed for classic muscle cars, late model muscle cars, street rods, street/strip vehicles, and trucks/SUVs.
