      Construction and Appearance. Constructed from 16-gauge aluminized steel, this muffler is fully MIG welded to ensure maximum durability and longevity. It features an enlarged oval case finished with high-temperature black paint for corrosion resistance and a professional look.

      _x000D__x000D_

      Installation. Installation requires basic mechanical skills with a slip-fit inlet and dual outlet connections facilitating easier attachment. New hangers are needed as the muffler uses a mount system that does not include hangers, and some adaptation may be necessary.

      _x000D__x000D_

      Application. Designed with universal fitment, this muffler requires some adaptation during installation and is suitable for multiple vehicle types including classic muscle cars, street/strip applications, and trucks or SUVs.
