Find a wide variety of upgraded and replacement up-pipes for your 2004.5-2005 Chevy/GMC 6.6L LLY Duramax. Due to age and heat cycling the stock up-pipes may begin to experience failures such as cracks or leaks. This will often result in symptoms such as exhaust noise, soot buildup, and slower turbo spool. Aftermarket up-pipes will not only fix the exhaust leak but can also be an upgrade over the stock pipes. Smooth mandrel bent tubing helps increase exhaust velocity and turbo response time by minimizing restriction to the turbo. This results in a drop in your exhaust gas temperatures (EGT's) and gives you additional horsepower and torque. Shop all the leading manufacturers such as AFE, ATS, BD-Power, Bostech, Diesel Site, Dorman, Ford, GM, HSP, PPE, MBRP, and more, available at XDP!
