test pipes or cold air intake
Cold Air Intake for a 'whistling sound'.
Edit: Dammit Jayk!
Depends what you're looking for:
Increased power and sound - hfc's or tp's
Nice whistle sound from the engine bay - aftermarket intake (but you will lose performance)
My advice: Get the MD ART pipes, z-tube, new paper filter and call it a day.

Get a used HR y-pipe while you're at it. Little increase in performance, makes the exhaust sound a little meaner, and it's only around $75 if you can find one. I used to have the F.I. HFC's + HR y-pipe combo and loved the sound.
get the MotorDyne ART Pipes. Most HP/Torque Gains over HFC or Regular Test Pipes. Dyno Tested 

Ill try.. i have to paint my car, specially the front bumper and the rear.. get updated headlights. lol.. and the Tp's




. Let's just all go back to stock!
