Cooper S JCW Pro Tuning Kit. Motorway refinement

[Goatex]

Looks to get said upgrade on our F56 Cooper S. Read all the good stuff about it however cannot find any reference to motorway refinement compared with the standard set up so just wondering if it is noticeably noisier when cruising? There isn’t a car locally I can find with it so before I make plans to go and sample one further afield I would be keen to hear from those that have it - if it is a constant drone at cruising speed in ‘quiet’ mode then will think again as need to to the occasional long trip in it.
