ok I am trying to get my cat off so I can gut it and weld a pipe inside of it. I got all of the bolts off except the two that are on the hanger that hold up the cat. It is tricky to get at. I have a breaker bar, but I cant get a good angle on it. Are there any tricks to getting bolts off easily? I did spray a little liquid rust on them, but it didnt get them off.

 

Well, that Liquid Rust you're using won't help your situation at all.

Try using short/hard pulls on the breaker bar instead of a long constant pull.

Have you raised the car at all? My bolts came off easily... maybe you need some height to get a good angle on the bolts.

With the breaker bar on get a hammer and tap the bar. Not hard hits just good solid ones to help break it loose.
