Can he not use a dremel and some of those reinforced cutting wheels? I used those to cut some off of my hf manifold and it cut through like butter.

I went and bought a 2 1/8" hole saw today, $17, kinda sucks I'm only gonna use it once. Anyone else want to buy it from me to do theirs, I'll sell it cheap whem I'm done with it ;) It would cut the right size hole for a t25 flange.

I had to match it so it would fit on the zc, you have to cut the bottom of the flange flat cause theres a little ridge on the zc that won't let it sit flush if you don't cut some off of it.

use a drill to make some preholes
then use a saw or a grinder...wtv

easier and more precise this way, make sure to trace with a pencil the hole u wish to create

AS for the warpage issue from heat if you use a torch or heat it up a lot, try setting the flange side of it in a pan of water. Worked for me...
