Dude I was terrified to replace my exhaust after studying the archives and list,  I sprayed with PB a few nights and knocked on what I could get to with a hammer lightly.  No problems with the replacement and the difference betweent the beat generic exhaust and the fresh OEM is night and day.  Go slow and own it brother!

Now it is time to tackle replacing the whole system. What sort of hell am I entering by pulling the exhaust bolts from the heads? So far I have only scrubbed them off with a brass brush and sprayed them with PB blaster a few times. Will heating the bolts with just a propane torch loosen the stubborn bolts or should I have the neighborhood welder hit them with the oxy torch?
