Aftermarket Exhaust Installed & Service Engine Light Came on

I don’t garage my car, but I do cover it, and it sits for days on end, so I’m sure some little varmint took shelter under there and then made a snack out of the insulation. Little bastard. The dealership wants $190 for the part and $130 to install it. That’s highway robbery as far as I’m concerned. I have a friend who can do it for free, but I have to order the part. The service manager gave me a part number of: 26AO-ET000. I would like to try and order the part from an outside vendor, so I did a search for it on google, but came up with nothing. Anyone have any suggestions on where I can order this from, other then from the dealership?
