I drove 2k before fitting the delete kit and have done 2k since. The sound in the cabin is 'cleaner' now the breathy slurping has gone ('-'). I did use a phone app to measure sound level before and after but could detect no difference. However it wasn't done under strict laboratory controlled conditions just me trying to drive in same manner at same speed along same road...!
