My CEL light is on and the dealer said it is because the cat converter need to be replaced. The Cat converter currently installed is an after market brand installed by the previous owner. Since I need to pass emission testing here in WA. Do I have to install an OEM from the dealer, or can I use an after market brand and have the code reset? if an after market brand will work, any idea which one should I use? Please help!!!
