AAAHHH yes.....the noise.

I mentioned this elsewhere, but just in case, I'll repeat it here.
I tried to get as much feedback as possible because it IS a lot louder than stock--but then, what isn't? Its the price you pay for lots more dial-a-smile! And besides, is there any better sound in the world than an uncorked 1050? I think NOT!! The typical reaction to the sound was a stupid grin followed by some form of "That's SWEET! (or BITCHEN!, depending on the age of the listener)." Its not obtrusive at cruising speed, just enough to remind you that your the man (or woman, as the case may be). I've already decided I'll have to come up with a removable db softener but that's no biggie.
With regard to performance, I let 2 mechanic friends ride it twice, once stock, and once w/ the new pipe, both agreed that it was WAY better. If anyone buys one and doesn't agree, I'll eat my Arai--or refund your money, including shipping--well, let's just go with the refund, I really like my Arai.
Having said that, I think I've decided to just make all the pipes myself. It'll take longer, but get to control things that way. So if anyone is serious about a purchase, let's talk.
