Need help identifying exhaust manifold and o2 housing...

[MarkyGsX]

Went to the junkyard today and scored an exhaust manifold and o2 housing from a wrecked talon...im for sure its not oem for the 1990 talon and it looks similar to a 2g exhaust manifold i just bought..except the runners about the same maybe slightly bigger but the exhaust outlet or collector is much bigger than the 2g....my guess was its an evo3 exhaust mani....any ideas...? also how can i tell what kind of o2 housing i have...its outlets are also much bigger than my oem and it is also more bulky than my oem o2 housing....hope this makes sense....thanks in advance

Did any of the manifolds come off of DSM's with Automatics?? Or are they all off of manuals.....?? Also, can you tell if any of them have been ported?
