    post the EBay address for that item. We can't read your mind which one it is.

    How much of an mph increase can you get with these ?

    mph is mostly set by port durations.
    reeds improve delivery ratio which improves power, mostly at lower RPM.

    none. that's not how engines work. there isn't a bolt on in the world that will increase your top speed. unless you count tiny sprockets, but then you lose acceleration.

    if you want more speed without impacting acceleration, add compression, retard timing, and raise the exhaust port.

    there are results, just not results easily measurable without a dyno. you could theoretically use a stopwatch but then human error gets thrown in the mix
