Product Details

Built with 304 stainless steel, this Stainless Works catalytic converter is made to resist corrosion, even in tough conditions. It uses a GESI high-flow, 200-cell metal matrix core, which is designed to let exhaust gases pass through more freely than a stock converter. This setup is rated for a 9 gm/cubic ft load, meaning it can handle a good amount of exhaust flow without getting choked up.

With an overall length of 10-3/4 inches and a 4-inch body diameter, it features a 3-inch inside diameter inlet and a 3-inch outside diameter outlet, making it a versatile option for many custom exhaust setups. While it offers improved flow and durability, please note that this converter is not CARB approved and cannot be shipped to California.
