Our Duramax oil drain line will work on any 2001-2016 Duramax. We use high quality braided stainless lines with billet aluminum adapters for both engine and turbo end of the lines. The turbo oil drain flange at the turbo has a high-quality O-ring seal instead of the cheap factory paper gasket. This not only helps ease of install but provides a better seal.
Machined steel 4.62″ flange (S400 flat V) for your S400 turbo. Most Borg Warner S400 T4 turbine housings utilize this style exhaust outlet flange. It has a machined recess to accept a 4″ pipe. Includes heavy-duty quick-release v-band clamp. The flange can be purchased separately without clamp NOTE: Clamp included is a VERY heavy-duty clamp. It is not just your standard cheap clamp that breaks the first time you try to take it off!
