    I got the Kooks 1 3/4" headers (catted) and x pipe. It triggered a check engine light. I wanna say it was the O2 sensor code(P0440 or something along those lines). He's not blowing smoke up people's asses. I figured I might have been able to get away with it with a catted header, but it still triggered a CEL. After a tune, no codes.

    Hey man got a question for ya. Thinking about getting Kooks 1 7/8 headers with off road xpipe. I saw in a post a while back that this tripped a sensor and you need to get a tune to turn the warning light off. Did it happen to you and is it something i should look into? Or is this dude just blowing smoke up everyones ass?
