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.

United Pacific exhaust elbow reducers can be used to repair, customize, or fabricate a new exhaust for your vehicle. The primary function of these components is to gradually reduce the diameter of the exhaust pipe at a bend, which is necessary when connecting pipes of different sizes. By providing a smooth transition, the reducer helps maintain optimal exhaust flow, preventing unnecessary restrictions or turbulence at the connection point. These steel exhaust elbow reducers are available in a range of styles, diameters and lengths to assist you in your exhaust system custom build or repair. Select the UPD exhaust elbow reducers needed for your application.
