  • Overview
  • Features

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. The 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.

  • 46% larger flow area over stock 
  • Manufactured from 11 gauge 304 stainless steel 
  • 304 stainless steel, internally-sleeved bellows 
  • Direct bolt-on replacement 
  • Includes 301 stainless steel gaskets
