Ok, I called them, I talked I guess to the builder and he said ICE racing and drag racing are what this pipe does best, he said the gains are alot more, cause it is a down pipe instead of a up pipe. He said, right off idle it makes huge power, but mostly in the top-end range. It costs $200 US plus $20 shipping here in the USA. I don't know about international. He said as long as the ice racing is on to the left, as the pipe mounts to the right foot peg. It comes with all bracket meterial.
It sounds promising! My phone died while talking to him, but that is the information I got. Let me know if you need any further information.
EDIT: They build the exhaust systems by hand after you order it, so it may take some time!
