ok I want to make the 3.0 intake but my parents dont think i need any kind of performance parts..are there any other things that a cai can help with so they will let me have one? also does it change the sound much? if so, how so? like annoying ricer sound or "muscle car" type sound. Are there any muscle car type sounding exhaust/mufflers for a neon? im just not a fan of the can type muffler.

 

gives you a little bit better gas millage. it also gives a little more of a throughtyer (i cant spell lol)sound when you stomp on it.
