benny yes the big smile was there lol but the smile gets bigger the more you lay in the throttle. at idle the m4s were a deeper tone and a tad louder. didnt get to test em much as by the time i finally got it back together, took longer than i wanted to to a tech difficulty(had to make a trip to the kawi dealer for parts(which of course they had to order) but thanks to Mattz for hooking me up with the parts off his bike i was able to get it back together late and get a short ride in, and dont you know theyre calling for rain for the next 3 days lol
