Yeah, I've seen that kit for sure, but I refuse to pay that kind of money for a pipe with a few bends and curves in it lol.
All a guy would have to do is be slightly creative on how to design a midpipe that runs along the bottom of the bike. Dean Adams has already come up with a great design utilizing a muffler. His Keda RT-2 has a dual outlet. Someone needs to do a drag pipe just like that and then tune it with theoctopus. I'd love to run straights and I would, but I don't want to possibly burn my valves and hurt my engine. I would run them with a proper tune though!
