new testpipe back exhaust is on the way.. what should I do with the factory '11 cat+back exhaust? Is it worth anything,, craigslist, post here, or keep it?

I would think the cat is worth something to someone, but I don't know what any of it is worth, or is it going to be worth it for me to keep it and I just don't know that yet?

thx

 

keep it for warranty purposes

 

^+1 or if you plan on selling your car in the future. Cali people might want your cats for inspection

 

if I decide to sell it what is it worth? I'm not thinking I will get anything done under warranty and this stuff will just sit around... the exhaust has 13 miles on it.
