PPE OEM Replacement High Flow Up-Pipes

PLEASE NOTE: On 2004.5-2016 Model Duramaxs this kit will only fit with specific modifications, if you are unsure, please feel free to email us.

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
• Faster turbo response
• Lower exhaust temperatures
• Kit includes driver and passenger Up-Pipes and PPE 304 Stainless Steel Up-Pipe Gaskets
