My inspection is due for my 00' jetta mk4. I replaced the oem cat with a magnaflow one and now my ecu is throwing a 4022 code saying my cat isnt functioning properly. Where can I find a good price on a oem cat and downpipe that isnt going to crap out on me? Also If I clear the code and try to inspect it do you think it will fail on emissions? Thanks for any help.
