Doing the International Up Pipes, have q's

[BigGreen7.3Machine]

So ive been facing a pretty large up pipe leak and i would like to just take care of it once and for all. I'm ordering the bellowed up pipes and a wicked wheel from riffraff here soon but i was wondering if i need to order any o-ring's or hardware and such with these items. Input would be greatly apreciated

If you are just doing the up pipes no. But if you plan to take the turbo and pedestal to make it easier then yes.
