Are all 3/4 exhaust loud?

It's this one: www.revzilla.com/motorcycle/ogio-tail-bag?kclid=ff27e7fb-e0a1-4813-8844-5b9fbdf030f0&gclid=EAIaIQobChMI3775p9qu3gIVEbnACh24zQ4jEAQYASABEgL7avD_BwE

I've had one for many years, and it always adapted to whatever bike I had. Sold my last bike with it, and bought an identical one for the 10. Couldn't attach it under the seat, like on all previous bikes, so had to do it under the tail section, but it's hardly noticeable. That means it might get dirty if I catch rain, but it just wasn't worth trying to make the straps fit under the seat for hours. I used a carabiner under the tail, so it's pretty secure. Hope this helps.
