Up Pipes That Seal and Stay Sealed

The Duramax factory up pipes crack at the bellows from vibration — often where the EGR riser binds them — giving you a pre-turbo exhaust leak and frequently a turbo low-boost code. These heavy-duty stainless up pipes move with the heat and seal permanently, and many delete the failure-prone EGR riser entirely.
