Catalytic Converter Help
Hey guys, just wondering if anyone might have some advice or experience about doing the cats on my 2000 z28 LS1. I bought direct fit magnaflow replacements, so there should be no welding involved. The 2 bolts on the rear of the cats are all pretty well corroded and will need to be cut off and replaced. I am going to try my sawzall, but space is pretty tight under there. I used my ramps with a 2x12 piece of wood underneath them, to give me a little more clearance. I am pretty sure that I will be buying the O2 wrench for the sensors. The sensors and the bolts on the front of the cats were pretty stuck. I hit them with some WD40 and a 12 inch breaker bar, but they still wouldn't budge. Any advice for me? I don't want to cut the back bolts until I can get the front ones out, as this is my daily driver for the time being. Any help is appreciated - Thanks!

if you have a cutoff wheel that will work better for the bolts as the heat of the exhaust has made them pretty hard... for the o2s try some pb blaster or other penetrating oil wd40 is more of a lubricant also a 7/8 wrench is the right size for o2s if you dont want to buy the special wrench
