Your right there bob they do sound awesome,they just have a sound like no others,with less vibration. It's not called pretend bob it would be called replica. I may have do that I still would like to get a hold of one just to see what the changes are. They all have something different which can help I'd them. Like I know (and can tell) the different's between the 1st & 2nd versions of the 500 Twin. There is just small changes between them.
