I started removing my cat's to install the Berk high flow cat's., Everything was going fine, only had one knuckle banger. Then the last bolt strips. Not the head, the threads. Its the upper bolt on the driver side. Couldn't have been one of the nuts where i could just try to remove the stud, nope. The bolt came half way out before it stripped so now I cant even put it back together.

So here I am, car in pieces, and a bolt that will not come out. Nothing I have tried has made it better. I am half trying to vent and half hoping someone has a solution that I haven't thought of.
