Hi, I'm in the middle of the research so help will be great. If I purchase the HKS Exhaust for Mazda 3, will there be a CEL(Check Engine Lights) when you install it? I heard some people gets the CEL and some don't. So the people who has HKS Exhaust for Mazda 3, who has or got the CEL? Honestly, I don't want a CEL unless I have no choice.
By the way, I have 2007 version Mazda 3 Hatch.
