The Pusher LBZ-GT-S400 Max Compound Turbo System gives you the components to add a second turbo to your 2007.5-2010 GM 6.6L Duramax LBZ. Compatible with most BorgWarner S400 frame and Garrett Turbochargers, this kit includes a CNC machined and laser cut flange for flawless mounting to your Duramax engine.

Each base kit include the 3" Pusher Max Charge Tube that properly supports the factory y-bridge at over 70 PSI of boost. As an add-on, you can upgrade to the Pusher SuperMax Y-Bridge for even more horsepower and flow. The Pusher intermediate exhaust pipe is hydro-formed to smoothly transition and match the S400 turbine outlet, and is routed so no modifications need to be made to existing "low pressure" A/C lines.

Made for an easy installation, Pusher took the hassle out of hooking up your exhaust with this custom turbo system. The included 4" downpipe features a patent pending smooth-flow flange that installs without having to relocate the factory fuel filter housing, or A/C dryer. The S400 turbocharger is placed in the optimal location for minimal impact to the passenger side plastic inner fender, and for optimal routing of every component in the system.

Built with precision, Pusher components are TIG welded to produce beautiful welds and optimal penetration without impacting air flow. The overall design and location of all the components allows for easy access and installation. Once installed, your truck will breathe through the Pusher 5" cold air intake with large inverted cone air filter. All fittings, oil/water lines, nuts, bolts, hoses, clamps, and even wire loom are all included for a clean, and complete installation.
