hey, what year is your car? If it's 1989 or earlier you don't have the MAF sensor. So it would go air box to the pipe with the big silencer to the throttle body. I wouldn't worry about rerouting the tubing from the exhaust manifold. I belive it is for cold weater only. there is some kind of sensor/dealy in the air box(there was on my 89 at least) used to know what it does. But many people that do a cold air intake ignore it.
I know that this has been discussed many times, try a search on this forum and you should come up with some answers.
