I tryed to throw some pics up but my camera is broken. I will give you all the quick run down. First off, this thing is off the hook. This is the funnest car I have ever driven.

Take a look at he air intake that comes stock, it looks like a vacuum cleaner hose assembly. Take the assembly apart I think there are only two bolts. pull the intake assembly out of the air box. Once you have the hose assembly out you have to move the plastic wrap down the tube. Now you have to seperate all the hose ends from the Vacuum hose, they are held together with some type of glue. If you use a screw driver of a thin scraper you can pry them apart. Once you have them all apart you should have three plastic pieces and a hose.

The next thing you want to do is on the driver side front bumper, the black plastic piece needs to be taken out if you give it a little tug from the inside on the corners it snaps right out. you will need to modify that piece a little.

Nopw to put it all together you take the main air intake piece (the one that goes directly into the iar box) and cut a piece of the Vacuum hose maybe 5 inches of so. Attached that to the small to the small plastic fitting then attached the 90 degree piece. To keep the hose and the fitting together I used some black duct tape(you can use something different but I wanted more bang for my buck, and it doesn't look bad). Once you have all the hoses together put it down into the engine bay and re attach the air intak and the plastic hose and reinsert the bolt on that piece. from ther your move the 90 degree piece to either the top or bottom of the open hole where the black platioc piece was. Once you figure out if you want the top of bottom you either measure or questimate how much of the black plastic piece you need to trim off then snap it back into place. I found that at the top the 90 degree piece fits snuggly enough against the bumper and the tabs that it stays in place. From the front of the car you cant even see it hardly unless you are lookin for it. I noticed a little bit more response from it.

On a different note the exhaust on the new Xb's is funky. It had two Cats on it. The one you can see at the header, and under neath there is one more. The one underneath is half Cat and Half Muffler. Don't know if when you take that second Cat out if you are going to get hassled with at the dealer. The muffler at the end of the pipe is pretty much a straight through Resonator. I plan to take it off and just straight pipe after the second Cat.

Later...:doc:

Hassled at the dealer?

I think unless it sets off an error code/light, you have a related service issue, or go to sell it, you are prob. OK with exhaust/cat mods.. I had a Buick Skyhawk... completely desmogged. (Re-routed/removed vacuum lines, drained cat, removed filler neck obstruction, etc.). It ran on leaded regular when we were done. Funny watching the mechs. thru the waiting room window... one guy scratching his head, showing another, peeking, poking, getting another... guy must have said "he de-smogged it",,, "leave it alone and send it away" or something! They closed the hood, and nothing was said. That is, until I bought a new car. The last step was to sign the thing which said "the emmissions controls were intact and operative." I told them I couldn't sign that and why, and wound up selling it for cash to a small auto lot that didn't care!

Hey dont take off the second cat. I assure you it is in fact a CAT. I took it out and saw wha t it was and had to put it back. In the owners manual it also says that it is a CAT. The piece at the back just prior to the Bumper is the resonator. I took that of and just ran a tip out the back. It made some good sound and with the forced air intake i diffinately noticed a difference in how it drove.
