The S300/S400 Twisted Compound Turbo Kit for 2001-2016 Duramax's is designed a little differently than your typical kit. With quick spooling in mind we mount the high pressure turbo 90* sideways from its typical position which allows us to build the hot side exhaust pipe between chargers more than half the length of a conventional hot pipe. The Turbine housing is also rotated 90* from the standard position mounted to a custom pedestal. Doing so requires a set of custom 2" Stainless 11g up pipes (Included) which eliminates a full 90* bend in each up pipe (decreasing from the typical 3- 90* bends found in the standard Kits to 2- 90* bends) These two redesigns from a conventional setup result in quicker spooling and decreased EGT levels due to less exhaust restriction.

For Competition Use Only. Please Call to discuss horsepower goals and Turbo Options.
