      Construction and Appearance. This muffler is crafted from durable 409 stainless steel with a fully welded two-chamber design, finished with a high-temperature black paint to resist heat and corrosion. Its chambered oval body measures 13 inches in length, 5 inches in height, and 10 inches in width, engineered to provide long-lasting performance and an aggressive look.

      _x000D__x000D_

      Installation. The muffler utilizes slip-fit clamp-on and weld-on connections for the 4-inch inlet and outlet, requiring some adaptation during installation. New hangers are needed as they are not included, and no extensive drilling is typically required, making the installation moderately straightforward for experienced technicians.

      Application. This race muffler fits universal applications and may require adaptation to specific exhaust systems, making it suitable for a wide range of classic muscle cars, late model muscle cars, and race vehicles where mufflers are mandatory.
