If you got the little extra time to do it, find someone with a Honda and find out what lengths would work. Man, if I had access to a shop, I'd do it. Hell, you could throw some on any of your motorcycles, ride them up and down East Wahington, show them off, stop at the hoppin' parking lots, and MAKE BANK!! Just pull up to a late night stop light, give the throttle a couple 10 grand and up revs. Watch the eyes around you become envious. Rice boys are moneydispensing easies.
