Leo Vince Dyno info?

Have any of you members running a Leo Vince system on their V650 had any Dyno runs done? I've found some stuff on line, but it's either vague, doesn't answer my question, and/or seems suspect.

I am considering putting a system on my 2015 V650. I want a little more noise, and so plan on using the baffle (Db reducer). I am not looking for a power increase, per se (tho it'd be nice). I'm more looking for a little more noise, a weight reduction, and NO POWER LOSS. I do not want to blow hundreds more dollars on a "tuner" (Power Commander), especially after blowing Leo Vince money. Delkevic has posted Dyno runs on a similar model 650 with their system, and it produced a little more power, but only with the Db reducer removed (too loud...I guess I'm old now). When I inquired as to whether they had done testing/what results to expect when running the baffle in, the reply was that "it wouldn't make a difference" (which while not impossible, is highly improbable in my experience. Less noise usually equals less power with after market systems). Sounds like a B-S sales pitch to me. I requested any Dyno infor direct from Leo Vince. We'll see if they reply.

So basically I am looking for the "unicorn" pipe. Something that doesn't need to have the baffles removed to make power (at least not lose me power). Anyone know if the Leo Vince system is that system.

Leo Vince has a dedicated system for the versys. Looks nice. Leo vince exausts always sound nice. This is under my radar also.

Dont have the dyno access to prove it, but recently put the pipe on my 2016 and we did not lose any power. I feel its made the motor a little more usable at lower rpms, below 3500 is where it begs for an upshift now as opposed to 4000 before, which was unexpected and nice. And power is definitely much more accessible throughout the rest of the tach.

At the same time I installed the exhaust I also did new chain and sprockets, dropping the rear from 46t to 45t. Super minimal change but perfect to slightly adjust the rpms in my most used gears/speed situations. Even with a sprocket change that drops torque slightly the bike feels more powerful and responsive. I am getting 55-65 MPG since the exhaust and sprocket install (but also ride above 7000ft 90% of the time which helps).

For sure a little louder but not obnoxious at all, I exclusively use it with the baffle in and think it sounds great. Now this is not the 5-holed disc baffle that fits in-between the muffler and collector pipe, which must be installed while installing the pipe on the bike, I do not run that one. I mean the baffle at the exhaust pipe outlet, which is removable with an allen key and pliers anytime, some may call it the 'quiet insert'. I run the 'quiet insert' baffle at the exhaust tip all the time.

Hope this helps
