Product Description

   So you want to run a big turbo on your EVO?  Then we have exactly what you need!  This is our EVO bottom mounted turbo, tubular exhaust manifold. Made from thick walled 304 stainless steel tubing. Featuring multi-pass TIG welded joints and CNC machined 1/2" thick 304 stainless steel flanges. The ports are gasket matched and smoothed to perfection for the best of flow, each flange is surfaced for a leak free seal.

     With this manifold you will still be able to keep a full size radiator, OEM radiator hose, and fans.  Allows clearance for up to an S cover compressor housing, designed for smaller T4 turbos.  Will NOT work with the GT42.  If you choose the divided T4 flange option you will need to run 2 external wastegates.  The divided T4 version comes standard with our high quality investment cast merge collector. 

O2 housing and dump tube(s) can be made upon request, please contact us for more info.
