Alright so I believe that my cat conv is going out due to a rattling sound comging from the inside. This has been going on for a while, I have been procrastinating the situation. So my question is what is my best option in your opinion? I know that aftermarket cat converters wont pass visual smog. I dont see myself paying a vast amount to a dealership because I'm a college student and I dont have much to spend. Should I try to go to a jeep wrecking yard? They seem like theyd charge a lot for them though. I checked to see if Napa could do anything but he basically said I need to go to a dealership to get one. Any help would be extremely appreciated. Also I live near Sacramento if that helps.
