Installed with a set of 100hp ddp injectors so don't know if i got any egt drop compared to stock but really happy with it and i like the dual egt ports
well worth the $265

I just got my manifold in the mail yesterday and installed it right away..I was shorted 2 nuts for the turbo flange, and the instructions are absolutely horrible. Aside from those 2 issues the install went well, it fits great. I noticed 100-110 degree drop in EGTs, also cleaned up a bit of the top end smoke. Slight sound difference too. Overall I think it is well worth the money.
