Find a wide variety of upgraded and replacement up-pipes for your 2007.5-2010 Chevy/GMC 6.6L LMM Duramax. Aftermarket up-pipes can provide greater exhaust velocity and improved turbo response time by minimizing restriction to the turbo. This allows your engine to breathe more efficiently, boosting your horsepower and torque while also helping to drop the exhaust gas temperatures (EGT's). 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. 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!
