Do you mean the "drone"at 100kmh,I am hoping the new system will take this away.I want lots of noise at full throttle and it to be quiet when cruising.I am getting the 100mm tips because I think they will fill up the space more evenly.Did you listen to the alfa jack 156 clip to get an idea what it may sound like?I know it won't be that loud but it maybe too loud for you.If you are not sure why don't you wait and I will tell you if it is louder or not.A lot of money to spend if you are disappointed.Kanga
