I'd have to feather the throttle one direction or another to get out of that rev range anytime I hit it. Obviously that's no bueno; made the car damn near undriveable (I finally took the pipes out past the rear axle to get rid of it; partially to pass inspection but also just to make the vehicle more driveable).
Or are they referring to just that thrum that comes from sitting at a cruising RPM. Because as far as I can tell...that's just noise. It's what you ask for when you get an aggressive exhaust.

It's a dull hum. A dull, hollow, monotone hum. It could even cause vibrations in the car. You'll hear it more cruising on the fwy @ 2K RPM than you would at idle. For me, it ****ing puts me to sleep during freeway driving. It's a much bigger deal on your Camaro than your truck as your Truck likely has resonators and a design that aid in reducing drone.
Even on this coyote swap i keep mentioning we are using resonators.
It sounds like what you are describing with your Camaro is a drone issue. Im guessing your exhaust is custom from the headers back?
