Im sure it is the gnarly woods. It has the odvious bend that the desert does not. I still have it and would post a pic but to be honest I have never posted a pic online before lol. My computer skills are below average at best. Any way i did notice a difference. The gnarly falls on its face real quick while the pc2 seems to sighn off just a touch later. Just dont feel it was worth the 200 bucks. Maybe i would notice it a bit more if I did a back to back test. The bike sat all winter with the pc2 on it and it was like 6 months between trying each pipe. I dont want anybody to think I am bashing the pc2 because it has been proven to make more power than the gnarly. When i get some time i want to do an immediate back to back test then maybe it will be more odvious.
I've always heard the PC2 made more power on the dyno, but have yet to see the dyno chart comparison. If it exists, which if someone ran the comparison I can't imagine it wouldn't, I wish someone would track it down so I could make a better educated decision.
As for V force 3 reeds, I bought a set, saw how they fit and sent them back. This was just my experience, but others I've talked to love them. Even if they make more power in a dyno test, I question their longevity based on the poor fit I experienced. The set V force3 reeds I received and test fitted, you have to get the dremel out to make them fit correctly which was a deal breaker for me. Fresh oem reeds seem to work great, but maybe won't win the horsepower contest.
I'm also thinking about just putting a set of Boyesens on since I always had luck with those in the past. I just remember changing them out more often then oem when I was used to I used to put serious desert miles on my 250s.
