Product Details

Product Name: Down Pipes
Manufacturer: MBRP
Fitment Notes: 2001-2004 Duramax LB7

Up size your downpipe and hang on for monsterous power gains. The MBRP Turbo Downpipe removes factory restrictions so your turbo spins freely and moves more air. Along with reduced exhaust temperatures, your powerplant receives a serious boost in horsepower, torque and throttle response. If your rig already has an aftermarket exhaust, there's still a major flow restriction between the turbo and the exhaust. MBRP downpipes and front-pipes remove this bottleneck to let your oil burner run wild! Plus, the high-flow lends an even deeper exhaust note that lets your competition know what's up. Built from heavy duty aluminized steel or heavy duty steel so you can count on these pipes lasting for many years to come.
