Exhaust drone is a constant, steady, low, humming noise that usually occurs at a certain RPM. It is usually not pleasant and one of those things that you will instantly recognize once you hear it. The key is that normal exhaust noise gets louder with higher RPMs while the drone is only there at certain RPMs and usually goes away at higher RPMs. It probably has to do with the sound waves resonating at certain wavelengths.

It's kind of a loud humming noise usually at a certain rpm. I put a cat back exhaust on my 2006 charger. There was some drone but it didn't bother me. Just turn the radio up

An annoying constant noise or hum. It is generally discussed when at certain speeds/RPMs, such as on the highway where you tend to be the most consistent with speed.

If you don't mind the constant hum of an exhaust system, or you like to turn your music up while cruising, I'm sure it'll be fine for you. Having a soft top that already lets a lot of noise in, I'd be afraid to get an exhaust system that drones or resonates at certain RPMs.

EDIT: You guys beat me to it, apparently I'm a slow typer today.

Thanks alot!

I love having my music loud and I love exhaust sound...

So if my music will cover up the drone then I'm good to go. I have a hard top so it will keep some noise out

You live in Montana. One of your buddies has a straight-piped diesel pickup. Have him hook up to 8000+ pounds, hop in, and go for a drive. Have him drive @ less than 1500 RPM at highway speeds. You'll hear drone.

I had the Gibson, ughhh, I hated it. It does have a bad drone. Some guys like it, I couldnt stand it. I pulled it and got a magnaflow 4"x18" free flow. There was a write up on the forum about it.

Here is a sample of the incab annoying sound.
