I have a question on Dyno's.

when I look at the ones that have been posted, (mostly on v-mod.com) they all seem relatively close, no matter what exhaust is being tested. All the discussions seem to lead to total horse power. As I look at them, is it correct that the big hp number is at the range around the 8000 rpm level?

Any sites out there that explain what these Dyno's are showing us.

With the exception of v-rodders like KAZ and others that race does it really make much difference to most of us which exhaust we use as long as we use a pcrIII and the proper map?

I am finished with adding chrome and I now want to understand some of the performance options available for my V-Rod.

The dyno numbers you see are interpreted by calculating the force needed to accelerate a known mass to a certain speed over a give time interval.

Here's some links to dynomometer theory you can read over. Though most of them are product specific you can derive the facts by reading them all and seeing what statements are constant between them.

In a nutshell, a dyno is a window for you to see what power and torque you are making and when. Attach a air/fuel analyser and this helps determine your mixture at different rpms. As long as you use the same dyno before and after each upgrade.
