    Here's another topic... how important do you think an exhaust system is? If you think it is important, what's your take on the size of primaries and secondaries? Is bigger better?

    primary pipe length formula(top secret)
    (850xED)dividerpm=prim pipe length(in inches)
    ED=exhaust opening degree at.001 lift +180 degrees
    primary pipe diameter formula
    ((cc divide(Px25))v-{checkmark deal on calculator}x2.1=pri. pipe diameter in inches
    cc=cc's per cyl.
    P=primary pipe length.
