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.

Replacing your stock exhaust manifold and up-pipes should be the first step in building a high performance exhaust system. Pacific Performance Engineering exhaust manifolds are co-designed by Honeywell (Garrett) and PPE, using CAD software to maximize flow characteristics. The included up-pipe bellows are high-flow, internally sleeved, and manufactured from 11-gauge, 0.120 in. wall aircraft-grade stainless steel with a 2 in. O.D. The exhaust manifolds are machined from high-silicon moly cast iron; feature built-in bosses; and are pre-drilled and tapped for a 1/8 in. NPT EGT sensor. PPE exhaust manifolds will help lower exhaust gas temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Order the model recommended for your application.

Secure your pipes with Pacific Performance Engineering up-pipes bolt sets. Each set includes Class 12.9 alloy steel 12-point screws with a black oxide finish--engineered to be better. PPE's OEM design features an increased thread length to accommodate washer thickness (washers are included), two screws that are 5mm longer to accommodate the downpipe mounting bracket, and this PPE design preserves thread engagement whereas others do not. Contents: * (10) M10 x 1.5 x 32 bolt and washer * (12) M10 washers * (2) M10 x 1.5 x 37 bolt and washer
