Find a wide variety of upgraded and replacement up-pipes for your 2017-2019 Chevy/GMC 6.6L L5P Duramax. Over time factory up-pipes may begin to experience failures such as cracks or leaks, resulting in multiple issues, ranging from exhaust noise, soot buildup, and slower turbo spool. 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). 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!
