Hey Ramboamt. Your 2nd video from Bassani, which pipe are they usng on your bike? Is it the B1 or mega power?

 

From their web site, I'm not really sure as they installed the system for fitment on our bike and I never asked what the total system was, it is the B1 system header pipe and muffler and it is using the 4" straight can muffler housing.
I'm assuming the "Mega Power System" is the whole system from head pipes to muffler end. The "B1" designator is the style identifier.
Hope this helps in muddying up the waters.....

 

Thanks guys for the responses. I think I'm going with the short Meg. I think it sounds slightly better and it shows off the rest wheel a little more.
