Exhaust removal

[slug]

Hi all, i hope to replace my exhaust soon and was hoping someone
could give me any tips on how to do it without snapping a stud I have been soaking the nuts with plusgas hoping this will ease them a bit. Any more ideas would be great Ta.

Thats pretty much it really, they are probably more likely to unscrew from the other end than snap, in which case treat them as bolts when putting them back, or free them off remotly and put them back as studs with nuts !

I have seen exhaust fitters using oxy-acetylene torch to heat cease nuts to glowing red to free them.
