Help With Catalytic Converter Aftermarket or OEM ?

Hello,

This is my first post here as I generally just find the answers via search or from others threads but this time I could use help. I am a part time scrapper and do not have much knowledge when it come to cats so i do not know if these are OEM or aftermarket which will of course determine my course of action in regards to this exhaust.

Any help you provide will be greatly appreciated!

They have that after market look about them

Looks like two small domestic ($45 apiece) and two pre domestic ($25 apiece)

Them are 2 pres which are about $25-$35 EACH and 2 honey combs which are worth $50-$60 each
