Yep any 2T/3T gasket will fit, thought the original 3TGTE items are the graphite type, so take the heat a bit better. Given however the last time I priced one up (around $160 from memory?), and the 5 week wait, I simply used an aftermarket pressed item with High temp silicon, to good effect.
is there any difference in using a normal exhaust gasket compared to extractor gasket? would the extractor gasket be better since it is much thicker
