The Vevor universal catalytic converter set includes two high-flow converters designed for vehicles with 2.5-inch inlet and outlet exhaust sizing. Each converter features a honeycomb ceramic carrier, 400 chambers, and an integrated M18 O2 sensor port to support efficient exhaust gas purification. Built from heavy-duty T409 stainless steel, they are made to resist heat, rust, and exhaust system pressure. This direct replacement design helps reduce noise, improve exhaust flow, and address common exhaust performance issues. Professional installation is recommended for best results.
