Hello from Kansas. I pick up my new red '07 Busa Friday of next week. I'll post pics then. Thank you for allowing me to join your board. I've already gleaned a bunch of useful information from the board and can't wait to put it into practice. However, I do have a silly question. After looking at exhaust, why do all the aftermarket exhaust systems go 4-2-1? I personally like the look of dual exhaust. Guess what my first mod will be? LOL Thanks in advance.
