      Construction and Appearance. Built from 16 gauge aluminized steel, the muffler is fully MIG welded for enhanced durability and long-lasting use. It features an oval chambered body measuring 13 inches in length, 9.75 inches in width, and 4 inches in height. The exterior is coated with high-temperature paint to resist heat and corrosion while preserving its appearance.

      Application. Designed with universal fitment in mind, this muffler suits a wide range of 4 and 6-cylinder engines, muscle cars, street rods, trucks, and SUVs, though some adaptation may be needed during installation. It is non-reversible and requires new hangers, which are not included.
