Description 2001 – 2016 6.6L GM / Chevrolet Duramax High Flow Up Pipe Kit PPE # 116120000 *50 State Legal* (E.O. D-701-20) 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 while maintaining a direct bolt-on fit to your factory manifolds. 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.
