I would like to thank everyone on the great input and info that's on this forum! I've decided on Cobra longs for exhaust,Metzeler for tires. Now will I need to get a fuel management system and different air box-filter when the exhaust is installed? Also heard about a management system that adapts automatically to any additions that one makes to the motorcycle.Anyone heard of this? Cost is around $500.00 for it. Do not know the name of the product as I heard about second hand.
