Hey check out what Leo just posted at the end of this thread... this explains all the trouble I have been having. The stock manifold is re-feeding the EGR gases back into the runners, I think everybody overlooked that. I always though it just fed back into the car.
I think I can drill some holes into the side of the runners where the bevel is and then just get two splitters and run the EGR gases out that way. That or copy the flange dremel. What do you guys think?
Wr manifold testers..
