Thanks guys. I think that the headers would cost too much, and after finding out some information I think that just replacing the filter would be a good choice. The CAI's don't seem to work much under 4000 rpm, and they're usually over $200. I guess my next question is which would be better; a K&N filter replacement or an Apexi Air Intake filter? Difference in price of about $50, favoring the K&N. But I've read that the Apexi outdoes it.
And just in case you're curious, here are a couple shots of my new toy:
Hope they show up. She's real purdy ain't she?
Thanks again.
