We sold the house and are living in the toyhauler 5th wheel and the Versys is over 100lbs lighter than the C14. Less issues loading and hauling it around.

   I don't know if you've seen them, but I have some dyno charts on my site with that system. If you're running the baffle, it's still a power killer, cost 6 hp with the Black widow header and delk 14" muffler. The delk system is better at light throttle response than the BW, so the things you've seen on this thread is an attempt to bring the BW header up to all the goodness it can have across the board.
    I still have my c-14, but truth be told the versys is my daily rider. Much better suited to the dirt roads I need to travel daily.

After mucho drilling and testing of baffles, and after about a 100 mile ride on my baffle w/ 34 holes in it, today I finally had the bright idea to ride this setup with no baffle at all, just to see how "bad" the bottom end would be.  I know...I should have tried this from the beginning, but in the words of The Reverend Horton Heat, "I learn my lessons slow!"

 

It ran fantastically with no baffle!  I had really been choking it down with the 34 hole baffle, and IMO the 46 hole one wasn't much better.  With no baffle in place it revved quickly, pulled hard on top, and even chugged happily up a hill in 3rd gear at 2500 RPM.  I didn't even really notice any sloppy low end throttle response.  I really could feel all the ponies I'd been choking down.  The only complaint I have is that I have gotten used to the subdued tone with a baffle in place and  it now seems really loud without one.  I decided to hog my 46 hole baffle out with another 25 holes or so.  I haven't ridden with it yet.  Hopefully it'll be slightly quieter than no baffle, but perform like there's no baffle there.   If it dials back in some low end throttle response that's cool too.

So far, from my seat of the pants anyway, no baffle is the best baffle until I find out if my drilled out to F baffle is the best baffle.  I'm also looking forward to testing out the longer velocity stacks that Steve has started a thread about.  Mine are on order...hopefully they'll be here soon.

I'm now up to 60 some-odd holes drilled into the baffle/DB killer, which now resembles a cheese grater.   I opened up about half of the holes to 1/4" and the other half are 7/32".  The bike is really happy both on the low end and top end.  It's snappy down low, screams to redline up top, revs freely in between, and sounds good doing it.  It certainly isn't quiet, but it is not nearly as loud as without the baffle.  I have a pair of taller velocity stacks on the way and am looking forward to getting those in to boost part throttle and mid range power a little bit more.  Otherwise, I think I'm about done with my experimenting at this point and am ready to pile on the miles.

I'm beyond satisfied with the Shoodaben tune and the exhaust at this point.  The bike runs smooth and strong.

Here's the baffle:

I'm thinking about going this route, but unsure which slip on I want, I really like the Arrow X-Kone, but may go full Black Widow with the one 350mm cans, thinking the longer can may not be as loud

2.5 years later I'm still super happy with my setup!

I watched your video, it didn't seem overly load, as that is my biggest concern. Need to get the ECU out and send it to Steve

With the drilled out baffle in place it is certainly louder than stock, but reasonable.  It sounds nice without being obnoxious...in my opinion.

With no baffle it is much louder with a deeper tone.

Did you do wheelie suppression?

Thanks, I did speak with Steve today. I have a decat pipe coming, but also have second thoughts about doing the black widow headers instead, but I think I'll just stick to the decat pipe. I'm not looking for every extra ponies i can get. Looking for all the other benefits, mainly the smooth off, back on throttle.
I also like the Arrow X Kone muffler, but it's kind of expensive, so I think I have decided to go with the Yoshimura .
Steve seemed like he likes the wheelie suppression, but if the tune fixes the twitchy off back on throttle issue, I don't think I'll need it.
