With almost all the fox longtubes you try to install in a fox you will have issues with the steering shaft. If you are willing to pay someone to modify a few of the tubes and possibly shift the motor back a little then you can make them work. But, the Hooker long tubes aren't cheap either. For $200 more you can get a set of Kooks or Accufabs. You may spend that having the hooker modified. If your making enough power to need long tubes then its worth spending the extra for the right parts. With the shorty headers out there right now its not wothr the money or the hassle to do it for only 15 hp. I've made over 700 rwhp through a set of shorties. I've had the kooks also. At that poower level the kooks netted me about 30 rwhp.
