My header to cat studs broke on my equal length bbk headers. I took them out and have yet to try to remove the broken studs. There is about 1/2 on non-threaded surface to work with. Any recom's on taking them out? Also anyone know offhand the size of the studs i will need to replace them with? thanks for the support

Heres what I did

I had this problem with my headers also. Forget tring to get the rest of it out. Your just gonna make yourself frustrated. What I did was drill out the stud with a carbide bit. The hardest bit you can find and drill the stud out. Get a stainless steel bolt and nut and put it all the way through with a double nut on the end. Sealed just fine and now I have no problems unbolting it when I need to. Dont forget to use heat valve when drilling and anti-seize when you done. Good Luck

Heat them glowing red like the exhaust shops do if possible.This is the easiest way.

Penetrating oil likely won`t work and using a stud remover without heat will likely break the stud again.

Without heat,you will probably have to drill them out which is a pita.

The diameter of the studs should be 7/16" not sure on the exact length.
You could make your own studs using some 7/16" threaded rod cut to size.

Not sure how much meat you have to work with but I was able to put mine in a vice and untread the header around it.

place a nut over the broken stud and fill the whole inside of the nut with mig weld than thread it out. we do this all the time at work.....but heating it red hot in the first place is the easiest way.

heat the stud up with a torch and than melt a regular tea candle or any other kind of candle so that the wax runs into the threads. than put a set of vice grips on it and try to turn it out. the wax works better than pb blaster and anything else.
