Greetings, I just bought a 2002 Silverado and my first purchase for it was a dual exhaust caback system from LMC truck. The problem is, the truck is a rust bucket underneath. I went to unbolt the old one, and the bolts wouldn't even budge. Eventually I just started rounding the two nuts down. I would just take a saw to it, but you need the flange on the end to conenct to the new system. Even if I got the nuts off, I'm assuming the two pipes are going to be so rusted togehter they're not going to budge.
Any ideas how I can get this done?
If I took it to a shop, would they be able to do something about it?

Thanks.

 

Just cut the bolts with a sawzall and replace bolts withh ss bolts and ur good to go put new exhaust on and any shop could do it

 

They just won't touch it if you don't have cats.

 

Break the bolts or cut the heads off, then just a little heat last hit the studs out. takes about 5 mins with air tools.
