Just wondering how many people have had their car defected because of a lumpy cam?
Only reason i can think of is didn't pass EPA.
Is ur exhaust overly loud also?
youve must of had a loud exhaust to get picked up on
I've been done before cam though . Even with the stock catback on with extractors my car was still 5db over. Depends on who is doing the test. The guy who did mine said (she'll be right mate)
