Exhaust??? Besides the weight savings & the fact that it looks cool when heated up, what other pro's can I get out of it??? I made up my mind that I will be going with Yoshimura Tri-Oval w/dual tip muffler, but am 50/50 on a full titanium exhaust. So my fellow Busa Sisters/Brothers what do you recommend??? Thanks for your help in advance. Or if you got suggestions, let me know. Thanks again.
