My son-in-law who also rides helped me to modify the exhaust. We removed the single exhaust pipe, then proceeded to remove all the baffling, pulled the metal screen out, cut 8 inches off and put a single hole thru the middle of the small screen at the front of pipe where it connects to the dual pipes. Gave it one hellava good rumble, when sitting, and blows you away when going down the road. Getting 47 miles to the gallon now.
