MHI “2-Bolt Eliminator” Downpipe


An MHI O2/downpipe combo made for externally wastegated setups looking for increased flow rather than a direct bolt on.

Getting rid of the factory 2-bolt downpipe connection flange means it’s no longer a direct bolt-on, but allows the bend coming off the turbo to be greatly opened up for better post turbine flow. This is set up the same as the quick release downpipe that we offer in all of our manifold/hot parts kits. It ends with a flex section/bellow right by the transfer case area (that slips over a 3″ exhaust) to be spliced/welded to your current set up or a great starting point to build off from with all the hard parts done for you.

Flanged for an external 38mm MVS or 44mm MVR wastegate (please specify) and for a 1g/2g/GVR4/Early Evo/Colt etc (please specify).

-Upper section flanged for your wastegate.
-Lower section that ends with a flex section/bellow.
-Quick release clamp.
-Optional dumptube (+$80) or recirculated (+$200).
