ALREADY PROVEN TO 600 WHP!!!!
This is the ULTIMATE big turbo manifold for your Evo. It WILL NOT be compatible with your stock turbo components - this manifold is for big custom turbo kits only! This externally wastegated T3 flanged turbo manifold features divided passages to the turbo flange and has the latest V-band style flange for easy wastegate installation.

In testing this manifold performed beautifully with absolutely no reversion in any of the passages. This is a big improvement over stock manifolds which actually blow exhaust gasses harder back toward the engine than they blow out of the turbo flange! Already the manifold has been dynoed at well over 650whp with as huge improvement in low end power, smoother running, much lower EGTs and allows more timing advance to be used without detonation problems. This manifold can't be beat!
