How do you get the cat off a 90 GS? Bolted SO TIGHT!!

I was going to take off the cat and put a straight pipe in its place because i want that extra power so i looked under the car and saw that it was bolt-on and im like oo easy so i break out the socket wrench kit and pull on it with all my might and it wont even budge, and im a big guy! is there any junk you can spray on it to make rust or oxidation or whatever is locking it in place go away??

Lube and breaker bar. When you get the pipe in spray anti-sieze lube.

lube like wd-40 or what? and whats a breaker bar

WD-40 should work. breaker bar is a bar that you attach to your socket to give you a long reach, there for more power. If you have lifetime warntee tools just put a pipe on your wrachet. If you have access to air tools get a impact gun and use that, should have no problem.

i used wd-40 and then i put the pipe from the jack around the wrench and hit that shit a couple times. Try it with a hammer if u need too. It is pneumatically tightened so don't think u are too weak....

i weigh 220 and i bench 265 so i wasnt thinkink i was weak.. i thought that it was just weathered on there or something... my friend said he had his car up on a lift and hung on the wrench and finally the bolt snapped

get a grinder and just grind that bitch off

i was going to just hollow that crap out because i have no money right now and cant afford a test pipe (i know how cheap they are too)... what kind of junk is in a cat, its it really messy?
