I'm not really sure what the brand is but all I think the rider did was move his standard highs by bending then inwards. The pipes look like they are at an angle from were the S bends come up, to were the cans come together. I might go and see if I can move my highs into the same position. I'm sure that one would have to get the spring that holds the can to the S bends re-welded. Looks pretty dang cool, and it would be something not to many peopel would have.
You can get an idea of what's involved to get that to work. That beiing said, if you can get the cans mounted up under there like that, then all you need is a custom "s" pipe to match up with the header. IF you knew the people who could do that it might not be much of a problem.
I've heard that space is a problem with a setup like that. The rear tire will rub the exausts at full compression. To aleviate that I beleive you have to cut the rear subframe to allow the exausts to be mounted up higher. I believe when this is done people go to the 9** tail section as well.
I also looks like he has trimed the subframe back farther that most hack jobs to tuck it up more. I would like to copy his bike but have to wonder how it would effect travel. When I mounted my Ohlins resivoir under my seat it hit the subfender (I think during some wheelie antics... purley accidental of course.. really officer!) 8)
it looks like the s bend pipes come up norma, then the cans angle in to the center line of the bike, and meet just behind the tail light.
would that give the wheel enough room when the suspension compresses? l
