My CAT is clogged. It is disconnected at the header. Now Im just trying to get the bolts off the other side of the CAT. They are rusted on good. So I got a grinder and cut the heads of the bolts off. Didnt touch the nuts because I didnt want to damage the exhaust piping Im still gonna use. The heads of the bolts are cut off. I cut into the CAT good you can see the outline of the bolt in the metal. I put PB Blaster and hit the end of the CAT with a big hammer and wont come off. Even tried a chisle wedge in the 3 corners no luck. Any ideas?? Maybe get it red hot with a torch??

-Thanks

take the bolts off the cat where there are 3. I got the side where the 2 bolts are with springs. STUCK

you put penetrating oil and all that on there?
i had a similar problem but just lubed em up good for a while and went at it hard and they broke loose.

FYI prob not the best idea to torch anything with penetrating oil all over it. haha

i had same problem. i unhooked my hangers on my exhaust and wiggled my exhaust around untill the cat was out the side of my car and went at it with a hack saw since i didnt have a grinder... you can try it that way if you want.
