The PPE Replacement High Flow Up-Pipes (part #116120405) increases both the flow and reliability of your 2004.5-2005 Chevy/GMC Duramax LLLY 6.6L. Even a stock Duramax can produce high temperatures and pressures that cause OEM up pipes to eventually fail from constant temperature and pressure fluctuation.
PPE has taken the OEM replacement to a new level. PPE OEM Up-Pipes allow 53% greater flow over stock, and 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 PPE's superior 304 stainless steel, internally-sleeved bellows that can take the abuse of high temperatures and pressures. Uses stock exhaust manifolds and hardware.
Important Note: $150.00 Core charge applies, reimbursed upon return of good core components to PPE. PPE product finish will vary.
