I have a used cat and dpf that I removed. Is there any legitimate buyers of these items? I could use the bucks but what Ive seen so far sounds like scams.

 

Check your local yellow pages for recycling companies that buy copper aluminum etc. and get prices from as many as you can, or auction it on ebay. If you go the auction rt put for recycling use only in the auction because if they're like catalytic converters it's illegal to sell them for re use
