Hey guys/gals I have an 06 cbr6oo which I have removed all but one screw required to take off stock exhaust. The left over bolt (hex) head is stripped. It's the bolt near the brake fluid reservoir and does not direct affectly the removal of pipe, but attatches heat shield to frame. However I cannot take the exhaust off. Do I need to take of completely ALL the side heat shield inorder to take off exhaust. ps once the bolts are removed from tail is the muffler suppose to drop easily. My doesn't and can't seem to locate any bolts / screw holding the muffler in place.
