Make sure there is no debris in the headers you plan to install: welding slag, foreign objects, etc. Run a bottle brush down the insides of each primary and where the turbo and wastegate attach. Some people knock these areas with a hammer in an effort to loosen any welding slag. MAKE SURE TO BLOW THE HEADERS OUT when you are done.

Great advice, I've see many new, expensive turbos trashed by weld slag, spatter, etc. One old method that really works is to buy a length of chain that will fit through the bends and spend an hour dragging it back and forth through each pipe with extra focus on the unseen collectors.
Don't break an exhaust stud. Penetrant can work but if you can't get the nuts off without moderate pressure on a short wrench pack it up and take it to a someone who can. Removal often requires proper application of serious heat. Arrange a time you can watch and learn how it's done then NEXT time you'll have the right tools and technique to do it yourself. All turbo engines have problems with exhaust stud/bolts breakage.
As Rarly says loose installation of all the components is another requirement of these exhaust systems, followed buy careful overall drawdown.
