My list:

First decide on K&N drop-ins (with maybe post MAF tubes) or CAI - depends on how much work you want to do (and budget!)

Then try HFCs (Berk) or test pipes (ART).

Than a Y-pipe (my choice will be Tanabe but there's a thread on the eBay one) or CBE.

Then possibly a tune and now you're starting for high $/hp items - NST pulley, Motordyne Intake Manifold, lighter wheels, lighter brakes (?), final drive gears, not sure what else - all too risky/un-economical for me.
