I looked at my records and saw that the header I got from Jett has a 1.5" rise, but the UHP Impact may not match mine.  Paul Walker is probably the guy to ask about which Randy pipe to use.  Which pipe works best may be a function of your exhaust timing.  One thing to keep in mind is that the screws that hold the header to the engine are 5-40s.  If you use 4-40 screws, you are screwed.

You could substitute 3mm x .6 metric screws for the 5-40's, Howard.  LL~ LL~ LL~ LL~ LL~ Steve
