Well.... I had been toying with the idea of replacing the exhaust on the V-Strom and decided to take Andrew up on his offer... After installation and about 800 miles with them I am really satisfied.

My thoughts and observations...
Installation was very easy, the only snag was having to loosen the passenger footpeg bracket on left side to get bolt threaded, off just enough where it wouldn't catch and I didn't want to cross-thread.
For quality and craftsmanship 8 out of 10 (if I didn't have to loosen bracket would have been 10 out of 10...)

Sound.....
It comes with two different baffles, one with a 28mm outlet and one with a 32mm outlet (this one was installed when I got it...) The 28mm is maybe just a bit louder than stock but sounds much better. The 32mm is definitely louder but sounds great. This is what I am using and at highway speeds there is no issue. I do find it to be a bit loud when less than 50mph at a constant 4k rpm, when varying the rpm it just sounds great....

Weight....
Stock exhaust was 25.5 pounds, the Wings were 12.5 pounds...

Performance.....
Prior to the installation the bike ran 94.5 hp on a dyno, In the next week or two I am going to custom map my PCIII for the Wings and see what improvement that they net... I will post results after the dyno run....
The bike seems to pull much harder at full throttle, when merging onto the highway I found myself about 10mph faster that I usually end up at. I guess the dyno will tell the truth....
One thing that I can say for sure is that at I am able to run at much lower rpm now.... Before at less than 2500rpm if I would go full throttle it would buck and stutter, now even as low as 1500rpm (not that I do it on a regular basis...) in higher gears it pulls very smoothly.

Heat....
I was concerned about how hot they would be as I do occasionally use soft luggage. Although the ambient temperature has not been higher than 75dF even after 70 miles at a constant rpm above 5k, I could still put my hand on both silencers. Warmer than stock and bordering on hot the closer you got to the outlet of the silencer but still able to touch. The connecter pipe is a different story.... As there is no type of shield there this does get very hot.

Overall very happy with the Wings Silencers, now I just have find out the real hp improvement they add....
