i am trying to get my exhaust off at the cat and its not coming off. its all corroded and stuff. is there anything that i can do to make it easier to get off? ive tried an impact gun and i sprayed a bunch of wd40 on it...still not coming off or even moving a little at all. any help would be appreciated.

 

Give it hell. Heat it up with a blow torch (make sure all the WD-40 is evaproated tho)

Don't be too dainty with the flange bolts. They WILL break, so you may as well just take 'em off with a sawzall.

 

I would go to pepboys and pick up a bottle of PB. I used it to take off my stock exhaust from the cat.

 

Keep trying, they'll come off eventually. Use a breaker bar.
