I have the Arrow full system, and really enjoy it. It changes the character of the bike some, and moves the power further up the RPM range. I did notice a decrease in midrange punch from 3000-5000 rpm, but then a huge power hit. A PCIII gave me back that midrange and more. The Arrow, and I presume the LV really smoothed out the whole bike. It pulls harder from down low now with fewer vibes, and continues pulling hard past 8000RPM. Effectively, I found the exhaust upgrade and the PCIII have widened the power band. I have excellent response from 3000-8000RPM. I will even bog the motor in lower gears down as low as 1600 RPM, and it pulls smoothly and strong from there.
I would say that the V is a very nice machine as is, and doesn't "need" an exhaust, but if you have the spare cash and want to have some fun... an exhaust is a nice addition. You don't need a PCIII, but it really makes a huge difference. Leo Vince is a nice piece of kit.
