Description
Race Performance Muffler. The Flowmaster 40 Series Delta Force Center/Center Race Muffler 4-Inch Inlet/4-Inch Outlet is engineered to deliver strong power performance while significantly reducing sound levels compared to open headers. Designed specifically for racing applications, it offers substantial decibel reduction without sacrificing engine output.
_x000D_Construction and Appearance. Built from durable 16 gauge 409 stainless steel, this muffler boasts a fully welded two-chamber design finished with high-temperature paint. Its oval shape and sleek black finish provide long-lasting durability and a professional race-ready look.
_x000D_Installation. The muffler installs using slip-fit connections at both inlet and outlet, compatible with clamp-on or weld-on methods. Due to its universal fitment, some adaptation may be necessary, and it requires new hangers which are not included.
_x000D_Application. This product fits a wide range of racing vehicles, though some modifications may be needed to achieve proper installation depending on the vehicle setup.
