With just the dinan rear section, you'll probably be just fine upshifting a bit early between 5 and 6. You need to be ridiculously loud to worry about a mobile sound check.

You can also ask for a sound check and not get a strike if you do go over. They will explain that in the morning driver's meeting. That's what I recommend doing if you aren't sure if you will pass sound or not without lifting.
