Diesel engines (even stock) produce high temperatures and pressures. OEM up-pipes eventually fail from constant temperature and pressure fluctuation.

PPE has taken OEM replacement to a new level. PPE OEM Up-Pipes allow 53% greater flow than stock. PPE OEM Up-Pipes are a direct bolt-on to your factory manifolds. But unlike factory parts, PPE OEM Up-Pipes are manufactured from 11 gauge 304 stainless steel and include our superior PPE 304 stainless steel, internally-sleeved bellows that can take the abuse of high temperature and high pressure.

Features:
•Direct bolt-on replacement to factory exhaust manifolds
•Significant reduction in exhaust back-pressure
•Free-flowing stainless steel inner liner bellows
•Stainless steel 11-gauge .120-inch wall, 2-inch OD Up-Pipes
