      Description

      Performance Muffler. The Flowmaster 80 Series Offset/Offset Same-Side-Out Oval Muffler; 2.50-Inch Inlet/2.50-Inch Outlet delivers a moderate to aggressive exhaust tone while providing enhanced sound control for custom applications. Its offset inlet and outlet allow for side exit positioning in front of the rear tires, optimizing fitment on a variety of vehicles. This muffler improves exhaust flow while maintaining a distinctive sound, making it ideal for classic and late-model muscle cars as well as street and strip performance vehicles.

      Construction and Appearance. Made from durable 409 stainless steel, this muffler features a compact 4.00-inch height, 9.50-inch width, and 13.00-inch body length in an oval case. It is finished with high-temperature paint that resists heat exposure and maintains its appearance over time. The transverse chambered design enhances exhaust flow and creates the signature aggressive sound Flowmaster is known for.

      _x000D_

      Installation. Installation requires basic mechanical skills with no drilling necessary, as the muffler uses slip-fit and clamp-on or weld-on inlet connections. New hangers must be sourced separately since the muffler does not include hangers or clamps, and some adaptation may be necessary to fit specific exhaust configurations.

      _x000D_

      Warranty. This muffler is backed by a lifetime limited warranty, providing long-term reliability and manufacturer support.

      _x000D_

      Application. Fits universal applications; some adaptation may be required depending on the vehicle and exhaust setup.
