HELP!! Rounded PITA top CAT bolt

abakja1 · 01-20-2010, 01:49 AM

Have a question,..

If the bolt head shears off, isnt the threaded part still in joining the header flange and cat flange together? Can someone verify this? Not sure how one can separate the cat from the exhaust manifold flange at this point....

I will try your method as well and ask my cuzn to hold the extension and socket in place as I torque it off...
