i am looking for a cat for my 2000 ex! mine is bad and i am wondering if a hi-flow cat will get rid of the CE light! if you have a high flow cat or anything that got rid of the CE light would be a great help!
Had that code. Got a new direct replacement cat converter from autopartswarehouse.com...I went with the DEC brand converter along with a new secondary o2 and the code has never come back since.^^^I've got the same problem man. Are you getting the P0420 code?
