i could be wrong, but when it came down to hp and tq, short ram and CAI made about the same HP, but when it came to tq, the CAI raped the short ram. am i wrong or right. right now i have a short ram. that thing sounds AMAZING, but as for performance, i dunno. water is not really an issue here in Tucson AZ, so i might just buy the 2nd half of the pipe and make me a CAI.
