Drone?

Is there a way to retain most, if not all, of the power delivery and top end sound while ridding the car of the drone? Removing the headers? Switching the exhaust? Tweaking the tune? It's a shame there's no free lunch but options are welcome.
I have the identical setup and dont have any drone. Are your secondary cats in place? I find this setup to be particularly fun because it's calm under 4krpm but all hell breaks loose at WOT. Lots of pops and burbles on demand

I have 3.73 diff as well and even cruising at 80 doesn't produce what I would call drone at 3200 rpm in 6th.

Windows up. - quiet
Windows down - riot
