I have a 98 Z28 with a SS hood, what do I need to do to make it functional, and whats the gains. As well I hvae a A4 with flowmasters and a Whisper Lid. What should my next mod be for some speed.

 

I don't know how to make it functional, but it will help bring some ambient air, and lower the under hood temp., I would go with headers, ORY and catback, after that you might want to beef up your suspension before you go much further with the engine.
