On the add a leaf install, Wire brush the threads and nuts you want to remove a few days before you do the work. Every day until you do the work hit them with some Liquid Wrench or what ever you use. The u-bolt nuts should come free with a breaker bar. Just cut the center bolt, it has to be replaced any way, so dont waste too much time if it wont lossen up- its under pressure and usually really rusted. I used two c-clamps to hold the spring pack together while I removed the center bolt, and used them again to reassemmble the new pack.
When I installed my cat back I just cut everything off, and replaced all of the bolts. Ive never had any luck getting exhaust fasteners loose - so i just go in cutting!!
Weapon (I mean tool ) of choice; Milwaukee Super Saws-All with a 14 TPI metal cutting blade.
If you dont have a saws-all I would buy it before a compressor. If you have the saws-all then yes you need a compressor!! For this job you mean- well maybe... but you do NEED a compressor. Its umm useful... for ... well you need one! I use mine all of the time airing up tires, running tools, blowing the garage floor clean, all kinds of things. I told my wife we needed a compressor in the garage so she wouldnt need to go to the gas station to fill her tires with air- I could do it at home for her- she thinks its great!!!
