So, test rode with stock muff and Arrow headers for about 75miles. I did not like the power, it seemed to have low spots in the fueling. Last night I put the Delkevic 14" stubby on with a longer silencer insert. Power = pulls easier from low rpm's, smooth and liner. Sound = Cruising / steady throttle - just right. Stab the throttle and you hear it - that is ok. Decel on the other hand is too loud. It's not Popping per say, it's just louder and raspy. I will try some tweaks to compression braking in the RB and maybe less fuel in the table at certain RPM's at closed throttle.
Also I have asked Delkevic what their expected -db is between a 18" & 14".
