Can i use an APN header on a 99 XJ??

okay so yeah my header is cracked on my 99 xj. seems like its pretty common. and after reading reviews and stuff it seems that the APN header is the way to go, but on thier website is says that its only for a 91 thru 98 cherokee. and not to order if your year make and model is not on the list, because ""It will NOT fit “other” 4.0L Jeep applications."" their exact words. but since people are putting these headers on with 99+ intakes why cant i just put it on my 99? so has any one put a ANP headder on a 99 xj and had it work out? and what if anything did you have to do?

I have an APN on my 99 but forgot about grinding the "runner" off. After a little extra torque to the bolts the "runner" popped of and the exhaust mounted flush and sounds good after 5000 miles.

It will works as stated above but I had to not only grind the #6 runner but also #1 runner. Otherwise upon start up there was such a vacuum leak the engine would redline almost instantly.

The great thing about UDP jokes is no one cares if you get them or not.
