i run Big Growl on my S&S113, I put 3" baffles in them cause I live in a 55+ neighborhood and the top end on the engine makes so much racket that I took the baffles back out. lol

If you search online for Cat Ears Cycle products, you'll find a fur-like attachment that velcro-attaches to the strap in front of your ear on half helmets. It was originally designed for bicyclists, but I thought I'd try them. They do a wonderful job of cutting down wind noise. I can even get by withou wearing earplugs, can hear approaching cars, how well my bike is doing, and not have to worry about high frequency hearing loss.
Loud pipes are helpful,yet I would like to think the riders who have them realize their limitations.That old lady/old man usually can't hear much,even less with interior noise in the cage & windows rolled up.
I went thru a period riding with loud pipes V&H Cruzers & put the quiet baffles in,which helped a bit.My current ride has the stock pipes with some homemade enhancement to improve the overall sound.At idle I can easily talk over the motor,yet a hard twist will wake up the pipes & draw some attention.
stay safe & enjoy the ride
Agree Blurplebuzz, Rex's pipe are modest at idle and cruising, but he does speak with authority when I open the throttle!
Back when I had the Dragon Bike with up-sweep fish tails I installed a set of "Thunder Monsters" which are very short baffles that are installed exactly 6 inches from the end of the pipe. Not only did they sound better, they made that Mouse Motor come alive.

Here is what the Thunder Monster Baffle looks like that I used.......
When I rode the 400 I took the sportster muflers off and welded on strait pipes out past the rear wheel.
Now with my VTX 1300 it has Cobra strait pipes on it. Love them loud they have both saved my butt.
I put the V&H true duals with oval pipes on my 2010 Ultra. My wife said after 100 miles she was deaf and couldn't holler any more. I was kinda pleased with the sound after a hundred miles or so. Anyway, I ordered the quiet baffles and put them in. Mellowed out the sound a little while just cruising, but still talked pretty good when romping on it. Also gave the engine a little more back pressure and could really tell the difference in throttle response.
