      Description

      Performance Muffler Solution. The Flowmaster 50 Series Big Block Dual In/Offset Oval Muffler; 3-Inch Inlet/3.50-Inch Outlet is engineered to enhance horsepower, torque, and engine efficiency while providing a mild exhaust tone. It is designed primarily for heavy-duty trucks, SUVs, and motorhomes where sound control and performance gains are essential under load.

      Construction and Appearance. Crafted from 16-gauge aluminized steel, this muffler features fully MIG-welded construction for durability and longevity. The exterior is finished with high-temperature paint and designed in an oval shape with a chambered internal structure that maintains quiet interior resonance while delivering a mild stock-like sound externally.

      Installation. Designed with slip-fit dual inlets and offset outlet, installation is straightforward with clamp-on or weld-on connections requiring no special drilling or modification. Note that new hangers are required as the product does not include them.

      Warranty. This muffler comes with a warranty that ensures reliability for the life of the product.

      Fitment and Application. Fitment is universal with some adaptation required. This makes the muffler suitable for a wide range of truck, SUV, and motorhome exhaust systems without specific vehicle or model restrictions.
