I am trying to install a high flow manifold for a B5 A4 and it seems some of the nuts can't go on the studs because the exhaust runners are to big, is this a common problem and also do they have a special install kit for these manifolds I am currently using an oem install kit? Also does anyone have instructions for this install.
Try loosening all the nuts and pull the manifold away from the head just enough so that you can tighten the seemingly impossible ones first with only the tips of the studs exposed thru their holes. This will keep the nuts tight to the header flange the whole time and away from the bulky runners.
