Anybody got any ideas for a beginner to get horsepower numbers up and quarter mile times down on my bone stock 89 Formula 350 Firebird.  I have been told Hooker Super Comp headers and a Flowmaster cat-back exhaust would give me a good boost I can feel.  On the in-take side, I have also heard good things about a K&N cold air intake system, but it doesn't look like they have a kit for my car.  Will slapping a K&N filter in there do much for me or should I try to find a shop that can custom fit something for me.  I would prefer to do all the work myself so I can learn.  I am good at general maintenance type stuff, but like to think of myself as a fast learner.  Plus I got the motivation.
