To get the best sound out of your car, you should look into the K&N Intake system. It will give you the growl you are looking for, but still making it smog legal.

Any kit in particular? I have heard open cone filters give a better noise? I searched k&n website and searched products by make and model and the only sell panel filters for my model? I guess it's gonna be a universal k&n cone?

Go with the panel. A cone will only suck in warm air from in the engine bay. You want cold air entering your engine. A filter won't give you a "tuned" sound. Personally I'd stick with an OEM filter, K&N filters allow more air, plus more dirt into the engine and no real benefit except you don't replace them every 30K , you clean and oil them.. Get a good set of mufflers on the car if you want a tuned sound.
