      _x000D__x000D_

      Construction and Appearance. Built from durable 409 stainless steel with a fully welded 16-gauge thick two-chamber design, this muffler incorporates Flowmaster’s proven Delta Flow technology, which eliminates internal packing to prevent blowouts. It features a high-temperature painted black finish that improves durability and resists corrosion under racing conditions.

      _x000D__x000D_

      Installation. Features slip-fit inlet and outlet connections compatible with clamp-on or weld-on methods. This universal race muffler may require some adaptation during installation. No special drilling is necessary; however, new hangers are needed and must be sourced separately.

      _x000D__x000D_

      Application. Suitable for universal applications with some required adaptation, fitting classic and late model muscle cars as well as race vehicles, offering versatility across various platforms.
