Fmf is the best in my opinion I run the full system you can get your maps off this thread. I posted the one I use or you can google mxa maps that work quite well.

I just got the Dr.d for my 2015. Sounds like they are tailored to yamaha as dubach works with them. Also won plenty of tests among top brands. Haven't tried it yet but I'll kepp you posted

I run the stock exhaust with a Pro Moto Billet End Cap. This allows me to run in the CA State parks (needs a spark arrestor) and does not mess with my Yamaha suggested FI map settings.

Did you notice any change to the power or decrease with the PMB endcap?

Not at all.

I noticed a bit of real low-end torque drop with the Dubach slip-on and sparky.  Considering just using the PMB unit for this reason.

Ghill, was there any noticeable gains? Smoother? I would be ok with losing a bit of that raped ape feel. Not sure which map im on exactly but its next to last in terms of trying to smooth it out

It seemed to rev faster through the mid. Less punchy for sure off the bottom. I wanted even more yank off the bottom than stock, but my other bike is a 325cc 2 stroke so I'm used to pretty aggressive power.

+1. I have the Dr.D SS version because it has the same core as the carbon or ti mufflers and the cost is just about on spot for what it worths. Besides being a tad heavier than those versions, it is more resistance to impacts, easier to repair and alot lighter than the stock unit.
