Look in the 2.0 and 2.5 forums, it's been done and documented as far back as 2002 if not further back. I'd start with the stickies in each forum.

Drill a hole and weld in a bung. Not enough material to tap.

True dat! Not to mention the possibility of tapping too deep.

Factory exhaust manifold yes? If so there is much more material there to drill thru than an aftermarket stainless header.

About 1/8" minimum material thickness is the general rule of thumb. I like it thicker myself.

There's a little raised up casting button on the stock driver's side portion of the manifold that most people use for tapping on the stock headers for an EGT gauge. There's plenty of material for tapping and threading in an EGT probe and I did this on my old WRX and it work great. I'm sure a welded bung would be ideal but, it's not necessary.

i drilled and tapped my stock exhaust manifold. it's been fine, and does not leak.
i also didn't want to remove anything, so i did it when the car was running.
did it that way with no ill effects on my Legacy and my old Eagle Talon..

Vibrant makes a 1/8-27 bung which should accomodate most egt sensors. Drill hole and weld said bung
