installing exhaust

[94civic94]

i have just bought exhaust for my civic and i can not get the bolts from the cat off so i can not take off my old exhaust they seem either rusted really tight or both if any one has suggestions on how to lossen them or something please help but i dont really feel like taking it to the auto shop b/c they will charge me to put it on b/c they dont let you leave w/ out exhaust on your car so i have no clue on what to do

Use some sort of penetrating spray (wd40 or better). Then use a impact or a really long breaker bar.

Amen.

I hate it when screws and bolts dont come out. It can give me a heart attack sometimes.

That stuff won't work on rust, trust me. I helped my friend install an exhaust on his rustbucket and we ended up sawing the old ones off and putting in new bolts. I have an electric saw thought, that made it 10x quicker/easier.

saw the bolts off...chisel (sp) and hammer...good ole fashioned force. my dad always told me that if something couldnt be fixed with a hammer or sawzall, then it didnt need fixed. i questioned him, but im beginning to come around.

Even if it doesn't come loose with the impact gun then it will probably break off anyways. Just try till it comes off, it will happen sooner or later.

i finally just took the bolts off behind the cat w/ the whole exhaust and those bolts were like welded on im just buying my friends cat from him its better than a shitty rusted one
