01-04 GM DURAMAX OEM REPLACEMENT UP-PIPES

Pacific Performance Engineering Replacement High-Flow Up Pipes

Pacific Performance Engineering replacement high-flow up-pipes allow as much as 53 percent more flow than stock pipes, and they're a direct bolt-on to your factory manifolds. Diesel engines, even stock, produce high temperatures and pressures. OEM up-pipes eventually fail from constant temperature and pressure fluctuation. Unlike factory parts, these OE replacement high-flow up-pipes are manufactured from 11-gauge 304 stainless steel. They include internally-sleeved bellows that can take the abuse of high temperature and high pressure. Order the model recommended for your application.
