93 honda accord performance upgrade questions?
 

I have a 93 honda accord and was wondering what performance upgrades I can do to it...i seen at a website that a guy upgraded a ton of parts on his engine/exhaust. I am not a car guy whatsoever and was wondering what each of these upgrades would do for my car?

1.) stock exhaust to new chrome exhaust
2.) stock air intake to AEM chrome cold air intake
3.) stock fuel pressure regulator to new fuel pressure regulator

there are many, many more on this website, from which I read about the above upgrades:

This is a serious question, and I could use some help...I am not a car guy at all! Thanks.

1) a lot depends on what exhaust you get, GReddy is probably the most popular. It will add horsepower and sound to your ride.

2) will also add horsepower and sound.

3)Not really much point in putting an upgraded fuel pressure regulator on a mostly stock engine, those are normally reserved for heavily modified engines.
