Construction and Appearance. Made from mandrel-bent 3-inch 409 stainless steel tubing, the downpipe has a ceramic coating applied both inside and outside. This coating helps insulate heat, resist corrosion, and reduce under-hood temperatures, featuring a heat-resistant satin finish for durability and aesthetic appeal.

Installation. Installation is straightforward, requiring no drilling or modifications, as the downpipe mounts directly to factory locations using the included hardware. Factory oxygen sensors are retained for seamless integration.
