MPI came out with the first LMM Duramax compound turbo truck in 2008. Soon after, stock turbo/s400 reproduction kits were out and available to customers. We have learned that the new LMM motors were built with better internal components and can withstand more horsepower and torque than the earlier models. Customers that have MPI’s compound turbo kits can expect to have the highest quality kit on the market. Unlike the other companies out there, all the pipes are formed by hand and tig welded to assure the most perfect fit. You will not find a better fitting kit on the market than our own. When you buy an MPI kit you will not be short handed on parts. The kits come with everything you need to change from a stock truck over to a compound turbo set-up minus the tuning. In these kits you will get:

Powder Coated Pieces:

 Coldpipe, Intercooler Pipes, Intake with aFe filter, EGR blocker plate, Fuel filter relocation bracket, and Coolant tank bracket.

Ceramic Coated Pieces:

Turbo Exhaust Housing, Hot Pipe, and Down Pipe

Accessories:

Oil lines and hardware, header wrap, exhaust band clamps, silicon boots with stainless clamps, coolant hoses and hardware, LB7 up-pipe (included on the upgraded kits), fuel hoses and hardware, all necessary clamps and bolts for pipes.

This kit is for off-road use only
