don't do a short ram. if you are looking for some decent power. get an AEM cold air. it takes air from outside of the HOT engine compartment and feeds it to your engine. Look on EBAY and find one fo the $119 headers. They are actually just as good as the DC sport and stuff. I had a complete greddy exhaust from header to tip on my prelude and my buddy had in-expensive stuff of ebay and the same car and we were turning the same times.
Look into:
Cold Air Intake (AEM)
Pulleys (AEM)
Header (DC SPORT, GReddy, or EBAY)
Free flow cat (EBAY)
Cat back system (EBAY)
these things should actually give you about 20-30 HP. It will only make your gas miledge go donw, because you will wanna play with it more and you will be in the gas more often to hear the intake and exhaust. but if you drive it sanely, it will give a little better economy, becuase your engine will breath alot easier.
