Unfortunately, nobody can really make this decision for you.
My experience with videos is that it depends a lot on how good the microphone of the camera is.
I myself have a system from Maxi-Tuner under my clubman and I don't really get the sound on the video.
Especially the deep bass tones are often swallowed.
We will see if someone has been able to personally compare the Remus valve and JCW PRO and can say a bit of their opinion ... with closed valve that is quiet and silent.
thanks friend
