      Installation. Installation is straightforward thanks to slip-fit inlet and outlet connections and clamp-on or weld-on inlet options. New hangers are required but not included; however, mounting typically requires no drilling. Some adaptation may be necessary depending on vehicle fitment.

      Application. This muffler is designed with universal fitment in mind, accommodating many vehicles with some adaptation. It is perfect for 4- and 6-cylinder engines, classic and late model muscle cars, street rods, street/strip vehicles, and trucks or SUVs.
