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 301 Stainless Steel Up-Pipe Gaskets

• This kit works correctly with all emissions controls present for the 2001-2004 LB7 with Federal Emissions
