I can't get the fricken bolts loose to remove the old one. The nuts are lefty loosey right? They're pretty rusted

 

spray wd-40 on them

 

use pb blaster and let them sit for 30 min.

 

forget it bro, had the same problem and ended up cutting it off with saws-all......i got a few loose by using a very strong socket wrench and a breaker bar (piece of pipe you can slip over the wrench for leverage) ti worked on a few but one a blot on exhaust is used for a while it's almost as good as having welded pipes!

 

I've sprayed wd-40 on them 3-4 times and took a wire brush to them. Didn't really want to cut it off.

 

Try heating them up then taking it off. Metal expands when it gets hot so maybe that will give you what you need to get them loose.

 

I don't have anything to heat it up with or cut at the house. Everything's at the shop.

 

Well.... WD and beat the hell out of it with a hammer and see if it comes loose.

 

if its exhaust, then just start your truck and let it run for a lil bit to heat it up. just dont burn yourself

 

If you don't have anything to heat or cut with at the house, just wait until you get to the shop where you have your tools. There is no point in breaking your stones trying to get the exhaust off when you could probably do it much quicker with the right tools. Personally, I would just cut it off.
