      CONSTRUCTION AND APPEARANCE. Constructed from fully welded 16 gauge 409 stainless steel, this muffler offers long-lasting durability and corrosion resistance.

The muffler is coated with high-temperature black paint for heat resistance and an aggressive, clean appearance.

      INSTALLATION. Installation is simple with slip-fit clamp-on or weld-on inlet and outlet connections, requiring no special tools or complex procedures. The muffler requires new hangers, which are not included, and may need minor adaptation for proper fitment due to its universal design.
