I have a 91 civic hatchback and I just installed new headers and downpipe and when I turned it on it started to smoke I heard its normal but idk can anyone help me please
Did you clean the header off before starting it up for the first time? Dirts and oils can smoke from being heated up. Is the header coated with something? That too can smoke.
like child said.
my megan racing ss header did it the first time it was cranked and i cleaned it it stopped after a while.
That s**t smells horrible though lol.
