oem catalytic converter+o2(the one on the cat) sensor off a 2000 accord coupe 4 cylinder. had 25,000 miles on the cat and o2. taking any offers. but honestly, im lookin to get around $58 shipped at least for both, but throw me an offer, maybe ill take it, willing to take trades also, but more at what market value is for the items, like $100 worth of stuff. the oem cat is worth $800 new, and the o2 $200 new. things are used, but VERY good condition, have a pic of the o2 and cat. should be able to sell it for more around $100, but im sick of trying to wait for people to come up with the cash, had 2 buyers back out at the last second(both were for $115 shipped), cuz they decided they rather have a performance mod or body kit, instead of getting rid of their CEL.
