im trying to install my damn catback but i just cant get 1 damn bolt off the catalytic converter! iv been spraying it with wd-40 and PB plumber stuff.... it just wont budge! im even trying to push the ratchet with my foot and no use!!! the other bolt came off with just a tiny spray of wd-40 but this one feels like im trying to bend pure metal! i even broke a hammer( the wood part snapped) unfortunately i dont have a lift so i cant use a cheaterbar...any other solutions? i just sprayed it with the pb plumber stuff and now im just waiting...iv been working on this damn exhaust since 6 and now its 11:30...iv never experience this...ever....

 

its much easier if you had air compressor.

 

its weird...i think i might snap the stud bolt i broke all the bolts holding my muffler

 

Jack the car up as high as you canand use a breaker bar, a 16" pipe should do the trick.

 

i dont have any other jack or a peice of wood...
im stuck for the night...i think im just gonna let the lube spray sit for a couple of hours...then work on it early in the morning

 

i know huh... lolz... but yea... try letting the wd40 sit a lil bit but other than that... good luck getting that bolt off...

 

im screwed if i break the stud bolt...plus i broke my stock exhaust bolts so i cant really put it back on...ugh....i got skool tom in the afternoon...hopefully il get the exhaust on by then

 

go to walmart and get some map gas... heat the bolt up til it glows... while red hot remove it.

 

could that damage the stud bolt? i remember we removed a catback from a hot cat and it broke the studbolt or crossthreaded it easily

 

if all else fails then use the heating method. Good luck.

 

put the other bolt back in, tighten it down and try it from there. sometimes taking the other bolt all the way out puts too much pressure on the other bolt. also, support the catalytic converter. dont let all the weight fall on just one bolt, that too can hinder the other bolt from coming off. good luck.

oh, once you get the bolts off-anti seize is your friend...

 

I use a 12" piece of copper tubing that I slip over my wratchet to get some extra leverage on bolts like that. See if you can find something around the house similar to that.

 

put a torch to it or use the double box wrench method.

 

Like every one else said heat it up with a little torch from walmart/sears basicly anywhere sells them. Will make your ike 100 times easier.

 

LOL, your story sounds familiar...

When I received my TBE I tried to install it myself, I put the car on jack stands, then proceeded to remove the cat back. The first bolt was not moving at all (even with WD40), so I tried to remove the DP... that was even harder!!! At the end I couldn't do it so I took the car to Meineken and they did the whole thing for $75 in just 1 hour!

If you don't have the right tools (like an air compressor) you'll have a hard time.
