What is wrong with my car?

It sounds like I am riding a chopper.

So YANMM (mechanic) but I wanted to see if I could get some input before taking it in tomorrow. Today I was driving on the interstate and everything was normal but all of a sudden it sounded like someone nearby was driving a chopper or an intentionally loud sports car. Then I realized it was MY car. It's like a definite VRRRMM VRRMMM sound (very loud) and it happens when I press on the gas or accelerate but not so much when the car is going at a constant speed. It also happens when I shift gears (it's a manual). Everything feels like it's running normally except for the loud noise and the check engine light is not on. I have a 2001 Subaru Impreza. I looked underneath the car and as far as I could see there weren't any holes or glaring cracks in the muffler or the pipe that connects to it (not quite sure what I'm looking at though).
About a year ago my check engine light came on for a few weeks and when I brought it in they said it was the o2 sensor. It went back off and they said it was probably spotty. I didn't end up getting it replaced because I was kind of low on money and the check engine light didn't come back on. In retrospect I'm thinking this was probably a bad idea because some things online are saying the catalytic converter can do something like this when broken and I wondered if the o2 sensor issue could have led to a catalytic converter thing?
Anyway, any ideas on what this might be and how much it might cost to get it fixed?
