Exhaust, Right sound?

[TallRider]

This appears to be what I would like in a sound for my bike. What do you think?

I listened to the Tourque Loops clips and the F6B is distinktively different than the F6C clip which I think is more rappy if that is the correct phrase. I want a deep rich soft sound. Current exhaust is OK till you advance throttle and gets dampened on exceleration. The Bassani clip part No 2F17T sounds right but don't know what will happen if exhaust is shortened for the Valk. I sent them an enquiry will see what they say. ???
