Thanks for all the info folks!
I'd love to go with an ESS supercharger, but the wallet and savings have been dried up with my down payment and my other passion (watches, damn bad habits). I was considering getting an intake, but those are said there really isn't any HP gains are absolutely correct. Right now, I'm think about a tune and pulleys, but am curious about the X-pipe or cat delete. I live in CA, I'm assuming either of these mods wouldn't pass a smog test. Am I correct in that assumption?
