I still think nothing beats the look of the OEM pipes. However, I think Vandemon looks like it could have been original more than any other slip on option I've seen.
The dual modes is a big plus for me. The loud mode is louder than I'd want to have full time. The videos don't come close to doing it justice.
Really the only downside so far is that, yes, they were crazy expensive.
The cans on both sides appear to be much lower than the OEM system, which will probably reduce the lean angle of the bike (?), becoming the first pieces to hit ground when turning tight or fast. Not too crazy about the look of the right side can either, but that would be a personal preference sort of thing. IMHO OEM system looks best, but is too quiet, followed by Zard's system. The Zard unit offers optional carbon fiber bits and pieces and comes in black or stainless finishes, so you can take or leave those - and it to is pretty pricey, but not as expensive as this one. And then there's the potential Fi mapping issues and the OEM ECU's ability to keep up when you open and/or close the exhaust gate, leading to the potential need for a tuner to make it all work right. $$$$ But, as always, to each his own.
Setup a voltage actuated window switch to control the valve and find a TPS voltage value corresponding with a throttle percent where you want it to open up, then wire the manual switch in line.
In this way, it'll auto open at X throttle position, and close below it giving auto hooligan mode. By wiring the manual switch in line, you can disable it so it remains in quiet mode at all times.
Were I buying this, I would definitely wire it this way so cruising remains civil, and antisocial behavior is maximum antisocial.

That would be cool, but I was thinking about a module plugged into the OBDII port that is monitoring the bike, and only opens the valve in Sport or Rider mode, and when the Rozzers pull you over, a quick mode change to Road mode as you're stopping and it's silent and smooth again.
