Just installed mine from stock dp with AWE Touring to APR dp with AWE Touring. I do understand of the WOT sound but I think is a deeper growl not as trumpet like but each to their own
This morning was my first day of commuting with this setup and I spend about 45mins to about an hour and 15mins each way to work so I needed a setup with sporty sound but also bearable during my commute.
At the moment, my wife, which commutes with me didn't notice too much of the setup (since I didn't tell her). Also I do have few stretch of uphills and downhills so the down shift sound is much louder yet still bearable.
But the most important part as kDizz781 said no droning at highway speed. I was doing 70-80 mph at 2-25k RPM with no droning while my wife sleeps through the ride. So far I'm happy with this setup but will make my final decision once the weather is warmer with my windows down.
Here is my video of the before and after.
