I'm looking to get either a Z28 or (hopefully) an SS in October... probably a 99 - 00 to save on money.

I was thinking that my first mods should be
Whisper Air Induction Lid
K&N Air Filter
Fast Toys Ram Air Kit
SLP Loudmouth Cat-Back Exhaust (single tips)

any suggestions??
what kind of HP would this give me?

 

get a cutout too... makes a difference. don't worry about HP numbers, they are just numbers.
