Is a hollow noise from my Mitsubishi Colt normal?

My Mitsubishi Colt recently developed a hollow noise when revved; is this normal?

Hi Pat,

Just as it's difficult for you to describe a noise to us, it's very difficult for us to help analyse the problem from afar. A hollow noise could be caused by a hole in the exhaust (it would be there even when the car isn't moving) or it could be something else entirely. Best bet is to bring the car along to a good mechanic.
