This kit will allow you to install an S400 based Turbo on your LML Duramax. Replacing all of the OEM plumbing and y-bridge with high flow 3" diameter piping. Oil Lines are high quality stainless steel braided Parker Lines with the oil feed line routing from the main oil galley on the side of the engine block. We designed our down pipe to connect with your exhaust system V-Band and clamp which simplifies installation and does not require you to cut your exhaust system.
If you are not purchasing the turbo from us you must specify the brand of turbo you are using, some Turbo's you may be required to ship to use for mock up to build the kit.
Includes Driver Side Transmission Dipstick Tube which makes installation of the down pipe easier.

***NOTE: Down pipe is designed for Half Marmon style S400 exhaust outlet; 4.6" Diameter flat flange. NOT compatible with HX40 style exhaust outlet flanges.

***NOTE: Down pipe comes standard with V-band style connection on bottom to connect with exhaust system. If you want 3 bolt flange style connection it is an additional $75.00.
