Ok a while back when i got my srt exhaust the guy also gave me this 2, i know the small one is the o2 housing and the other the downpipe? or the catalytic converter, so my neon is a 2.0 non turbo, soo what can i do with this thing? i was thinkin of sellin them on ebay cuz i dont even know what they are for so anyone mind explaining to me?

 

you can use the cat on your car... Keep it incase yours ever ****s the bed. The O2 housing will be useless to you as an N/A car.

 

you can get some dough for teh o2 housing fa sho

 

^^ probably not, its a stock one.
