With nearly 3000 miles on the 2008 Hayabusa's clock I can't handle riding another foot without some sound.
I've ordered up a set of Micron's cool looking MotoGP style slip-on pipes (www.micronexhausts.com) with a removable baffle and carbon fiber end caps.
They come in stainless or titanium...i don't remember which ones I ordered though!
Hopefully they get here today or I'm walking home. Seriously.
Stay tuned for for some dyno numbers coming soon and a pic of them installed...
