Gonna put the full HMF Hi rise system on the Busa probably this week or next along with a PCIIIr. I need to find a good tuner with map skills and a dyno to get everything right in tyhe Tampa / Orlando area. Also looking for suggestions on other small improvements I should make ( With links to directions ) to compliment the exhuast changeover. I'm planning on installing an air shifter to make the 1/4 mile go by just a little faster
