Something under my car is rattling so I put it on a lift and hit it with a hammer - weird noises coming out of the cat, sounds like its broken. Check engine light came on and is throwing the secondary O2 code. Anyone have a catalytic converter and secondary O2 sensor they want to part with. OR give me a good idea to get it back on the road for under $300?

 

i have a cat ill sell you for like 60, pm me
