Diamond Eye Performance

Diamond Eye Performance is a leading manufacturer of heavy-duty diesel exhaust systems, engineered to deliver bigger flow, deeper tone, and longer service life than the restrictive factory hardware found on today's diesel pickups. Built in the USA from premium materials, Diamond Eye exhaust components are designed for the real-world demands of work trucks, tow rigs, and daily drivers that need to breathe better and last longer. At Stateside Performance, we stock a focused lineup of Diamond Eye products covering the upgrades diesel owners ask for most. Browse our selection of 5-inch cat-back exhaust kits in durable aluminized steel, single-outlet cat-back systems for a clean factory-style exit, and direct-fit muffler replacement pipes that let you tailor the sound and flow of your existing system without replacing the entire setup. These mandrel-bent components are built to bolt on with factory-style hangers and clamps, making installation straightforward in your driveway or shop. Diamond Eye fitments cover the heavy-duty diesel platforms we serve every day, including Ford Super Duty, Chevy Silverado 2500HD and 3500HD, GMC Sierra 2500HD and 3500HD, Ram 2500 and 3500, and Dodge Ram diesel trucks, with select applications for Jeep and Cadillac diesel-equipped models. Whether you're chasing better turbo spool, lower exhaust gas temps while towing, or just a stronger diesel growl, Diamond Eye gives you a proven path to get there.
