well if you want to wait a few days I could get you the route I took, I just need to find my digital camera and then I need to wait for my couplers to come in the mail so I can start cutting and fitting the pipes.. as far as the cai, I am a believer that a colder starting air temp only allows the IC to cool it more, or at least not as much, but then again, when it's hot out, it doesn't make a huge difference, the big difference I notice is when it's cooler outside, but that's me... again it has been debated forever and way to much.
back to the point, if you will wait a week I can tell you exactly (for the most part) where to cut, how to go and what pipes to get and whatnot, I have my main idea down right now, and my hot pipe side is all set mostly, just need to work out the cold side and the fitment with the 03 fogs and HID ballasts, but shouldn't be a problem once I get my couplers in, and I will not be going the cai way, my brother has a similar routing to what I want, but a different angled pipe, so I will be close to his, but I will get you the measurements based off of the CX racing kit, as soon as I can..
for now you should look at Wagon's link in his sig. the hot side for what Dub did is pretty much what I did, works great so far, but haven't tested the bumper out yet, and with a CF hood, I had no use for the windshield wiper fluid anyways, but if you want to keep that, look at CS FMIC instructions and do it that way..
