When I place the order with Jimmy at Torq Master, he asked about what I was looking for as far as loudness.
I wanted louder than stock but not really obnoxious. I told him if I was riding along side a car with a texting driver I'd want that driver to know I was there (hear me). He said he understood, and he also said he had small baffles that I could install if my passenger found the sound annoying during a long trip. They could be removed when I reach my destinatioin.

It may just be me, but I really liked the personal touch of talking to the man that actually builds the stuff.
