I have a cat from a 2001 superchanged bonneville that had gone bad. It rattled upon acceleration, and once removed from the vehicle, it's clear the ceramic cone stuff is loose inside.
I wanted to toss it in the garbage for the longest time. I replaced it with a $50 high-flow cat (I was suping the car up then), but am left with the old one. I know it's worth money, now what to do with it and how much? I am seriously considering just giving it to a coworker of mine that routinely has scrap metal in the back of his truck when he parks at work (there's several scrap yards in the area.) and asking him to get whatever he can for it, and give me a 12 pack or something for the favor... It was literally saw-zalled off (my own car), but that car I sold in 2013. Not sure I can get proof of ownership for the car. I'm simply tired of it bouncing around the back of my pickup, and I'll throw it in the trash if it's too much headache to get a bit of money out of.
