mc Posted June 25, 2013 Share Posted June 25, 2013 What bolt sizes do I need for the triangular flange on the berk hfcs? Appears the original cats had the studs integral to the flange, but the berks don't, and my exhaust is blowing as a couple of the bolts are missing now :-s cheers, Mike Quote Link to comment Share on other sites More sharing options...
mc Posted June 25, 2013 Author Share Posted June 25, 2013 Just found this post http://www.350z-uk.c...ng-of-berk-hfc/ If a Stud breaks then yes it would need drilling out or removing However ...... AFAIK The top has 3 studs/bolts and the bottom has 2. Both the bottom "studs" are part of the old CAT so if they break you only need them repaired if you refit them, they are replaced with a nut and bolt when Berks go on. 2 of the top "studs" again are connected to the CAT so same applies. The third "stud" is part of the manifold end and is the one you really dont want a problem with, if it snaps then you would drill it out and replace with a nut and bolt. so now i'm not sure if I have studs or bolts missing... probably M8 though at a guess?
