I am installing the c&l plenum and accufab 75mm tb. Would it be worthwhile to add a c&l mass air kit or maybe even just the inlet tube or just keep the stock assembly with a k&n and air silencer removed which is what I have now. Or should I just save the money and get a set of aftermarket headers, I have borla catback and bassani x installed but never added aftermarket headers in to the mix. Any suggestions. I would like some extra power but just dont want to spend the money if its not worthwhile. Thanks in advance for any help.
