Catalyic Converter Replacement HELP

How do I remove my cat? Does anyone have any pics or videos on this?? I'm pretty sure it's the problem but not 100% sure. For about a year or 2 my engine light has been on because of the cat. I never replaced it because it was running fine. Now when I drive the car it's having problems accelerating. When you step on the gas it sometimes doesn't want to go. And it seems to be getting worse. Would the cat be the problem or something else??? I don't have the money right now to fix it so I was hoping I could just take it off for now and drive with it off for a month or so. If I take it off will it damage anything driving around without one?? Also will the car be REALLY loud?? or have a bunch of smoke coming out of the exhaust?? I don't know what my other options are.. I'm hoping I can just drive with it off for a month or so... Can someone let me know please and how I go about taking it off if that's the problem. I live in Barrie, Ontario so even if someone could help me with it I'd be forever grateful... please help.

Moved to "General Technical Chat". Removing the catalytic converter is quite easy. But more than likely it's going to be a very rusty removal. There is a bracket on the front of the motor and one on the backside of the motor. There are also three bolts holding it to the exhaust manifold and two bolts holding it to the flex pipe. I removed mine after 5 years and mine was rusted so bad that the back bracket was broke in half. Plus there was so much rust under there that I had destroyed the flex pipe in the process to remove it lol. I am sure if you search on Youtube and on here you can find plenty of information on how to change this out.

REALLY loud without any exh. connected.

You'll need a pipe to replace the converter (or try to hollow it out) to reconnect the exh..

Look just past radiator, there is a tin heat sheild held on by 4 8mm bolts.Remove the to get to the 3 exhaust bolts. Unclip the O2 sensor electrical connector by the fan that goes to it. Then from under, the cat has a center band bracket you remove. Then the oil pan pipe bracket, and the exhaust connection bolts. Insure your ramps or jacks are secure/safely in place. All these things are visable, use penetrant like JB Blaster the day before. WD40 has a new one out, let us know if you use it-have good luck with that.

Well I PB blasted all the bolts today but still had no luck getting them off. I soaked the bolts again and am going to let it sit overnight. Both the brackets are completely rusted and the two bolts at the flex pipe are so worn and rusted that I might have to grind them off. Would I grind them at the bolt head or at the nut end? I don't want to mess anything up. Man I hate rusted stuff.

Use heat! torch that thing! should loosen up the bolts. Also if you can get an impact gun that would work well. I used an electric one though pretty buff and that got all the bolts out no problem.

I'm going to try again today. I have a little propane torch hopefully that will get the bolts hot enough. Say a prayer for me. :)

So I've removed some of the bolts. But the two bolts that are connected to the bottom pipe where it splits to connect to the exhaust pipe are completely rusted. So I think the only option is to grind them off. Does anyone one know exactly where I should grind it??? Do I grind off the head of the bolt or the end where the nut is?
