Does anyone have experience with Yuill exhausts for the CVOultra?  I'm thinking about them for several reasons......
power, sound and contributing to a cooler running engine.  I'm not wild about their looks, but form follows function and they're growing on me.

Living here in Reno where they are located a number of the HOG Chapter members run them.  I have only see one dyno print out, it was for an 06 SE Ultra, 103.  The only thing done to it was the stage 1 air cleaner and the Yuill Bros Exhaust.  Makes 101 hp & 100 lb ft torque at 4500 feet here in Reno.

I did a decible comparison of it with my 06 SE with same air cleaner & just SE Slip on Mufflers.  Mine makes 94 hp & 101 lb ft torque at sea level.  The two exhaust systems were within 1 to 2db of each other at all rpm's.  The noticable difference on the MC is the lack of noise in the riding area.  The rider & passenger can easily talk without yelling to each other.  The rider area noise level is very low compared to my SE.

The big deal is the lack of heat, they did an incredible job of getting rid of heat.  I like the system but as you say not crazy about the end cap look on the mufflers, however that is part of what makes them work.

The picture was taken more for the tour packs but shows the mufflers pretty well.

I have sold and installed many sets of these pipes. Fit and finish is at the top of the exhaust heap and they do perform very well. Compared to other systems out there such as the Thunder Header they have much more torque in the low to mid RPM ranges. On Erniezap's SEEG he got about 15 more ft lbs from 2000-4000 rpm than the thunder header. The peak numbers were very close.

The only area of difference in performance between the T-header and the Freedom exhaust is the Freedom torque is basicallyflat to slight increase up to 3000 RPM where the T-header has a big dip.  The Freedoms are a lot quieter when you aren't jumping on it.  When you grab a handful, they get loud.  The one thing that IS missing is the T-header growl...

Had my Freedoms now for just over a year and very happy with the results.

Thanking Jim for the recomendiation it was well worth the wait.
