I have been hearing a strange frequency when I am going above 60 mph all the to 80 mph, I will try to explain the best I can.

I thought it was my exhaust that is causing the problem, but then I noticed the sound only appears when I am crushing or when I accelerate from 60mph to 80mph, basically instead of a constant (linear?) "exhaust" tone, it gets wavy. Wavy like it would go from low to high and low again. could be the engine or the exhaust but I can't pin point what caused it.

it wasn't like this before so any help or info is greatly appreciated.
