Bare in mind this system is completely brand new.
Once the internal sound deadening material takes it's final position the sound on the loud becomes even more exotic. The quiet becomes more smooth.
Breaking in period is a little longer than we had expected.
We fitted one system 2 weeks ago. Customer complained about drone on quiet section which was unbearable. He did over 1000 miles in it in a very short space of time and reported that the droning had become hardly noticeable.
So just beware of this.
Look forward to VS's videos!
