Wander what it sounds like just normal riding without twisting it up, i think i could like it, would like to here it with the baffles in the brawlers.

I no longer have the phone that fly by clip was taken from so any chance of an honest over the net sound comparison is out the window but I'll see if I can give an example here of what Akrapovic headers and corked Brawlers sound like. Hope it helps.
What I have and used to do this is a $35.00 Craftsman Decibel Meter. Inexpensive yes but surprisingly accurate and I trust it to be very close if not with-in a 10th as it was in the side by side with the certified +/- 1.5 db. Fluke meter. Also Credit to Jay (he'll troll this I know) a good friend with me who had been bribed with breakfast and pistol range time to cox him out so early setting just off the side of the asphalt writing down what he saw and prepared to be my -Buddy- if need be.
Ambient noise out side was 51.7 db. Nothing but birds, bugs and a breeze.
At idle with meter in hand at chest height setting in the seat 88.9 db.
For the next set of readings the meter was close to 3 ft. off the side of the pavement on a 5 ft. stand, bike in 6th gear on level ground and maintaining steady speed.
50 MPH / 80 KPH 107.1 db.
55 MPH / 88 KPH 108.4 db.
60 MPH / 96 KPH 109.2 db.
70 MPH / 112 KPH 114.2 db. (buddy told me here is where it got loud to him)
90 MPH / 144 KPH 120.2 db.
Full throttle
128 MPH / 205 KPH close to 11000 RPM 5th Gear 131.1 db.

said he could hear me the whole time and I guess it to be a little over 1/3 of a mile or 600 meters as the strip is 3/4 of a mile long and we set up just passed the middle.
159 MPH / 255 KPH again close to 11000 RPM 6th Gear 130 "ish" cause he blinked when I blew by and I wasn't doing it again, had to use part of the drive way to the landing strip to get up to speed and still have room to shut down.
Here is one of the charts I've seen floating around also for an example of how loud things are.
