Need help removing dump pipe from ZD30

Im wanting to install a EGT gauge in the patrol but first Im removing the dump pipe to install the fitting. Gotta say..that heat shield cam off in 30 sec and Ive never done one before...lol I just thought as it came away what all the fuss was about..lol, maybe putting it back on might be a different story..Anyways Ive got the 3 top nuts off at the turbo and the 3 nuts at the bottom of the dump pipe and now my question is what best method to remove the dump pipe itself, still seems to be in pretty solid. Ive googles and searched but cant find anything other than removing the heat shield as the biggest problem....help please.
