I have a 93 civic ex and Im droppin a b16a2 si motor in it, and I am tryin to find out what is the best way to put performance intake on it. Also, I want to make sure that if i put a 99 dc sports header on it....will it match up good enough so I can put world sport catback exhaust for a 92-95 gen civic.....or do i need to get the exhaust custom fitted.
