I have the borla atak on my Gen2. So it's hard to compare to your R. I personally like the setup. There's no drone at any RPM, not loud at all while cruising 80 on the interstate, or on the street doing 40.
However, when you put your foot into it, the exhaust comes alive and is super aggressive and crackles nicely in sport mode when down shifting. It's also very aggressive on cold start up in high idle.
