02 Civic Si cat help
I got a 2002 Civic Si and its been throwing a CEL P0420 cat ineffeciency. I'd like to get a new cat converter but I cant afford paying over 1200 just for the cat and new 02 sensors. Universal cats are illegal in Ca. so whats the best option for me? Oh yea and my smog check is soon. Thx
