It sounds like "rrrrrrrrrrrrrrrrrrm"

Why did my car start roaring whenever I press the accelerator? Should I be concerned?

This past Saturday I had an oil change and replaced my fuel filter. On Sunday morning I noticed a new sound while driving; it could be the result of something Jiffy Lube did, or it could be a coincidence. The weather here started getting Fall chilly about a week ago too (I park outside).
Basically, when I accelerate I hear the engine rev up as normal, but now I'm hearing a second revving-sound too. It's lower in tone and loud enough for me and my wife, who's always a passenger in this car, to notice without listening for it. It's only present when I accelerate; driving at a constant speed sounds normal. I tried revving up while out of gear and didn't hear it then.
Because it's a louder-than-normal engine sound, I suspected my exhaust system and took the car to Meineke for an inspection. They couldn't find anything apart from a slightly wobbly exhaust pipe of some sort under the middle of the vehicle. The mechanic said it couldn't be tightened, but maybe it's expanded/contracted with the weather over the years and now it vibrates when I drive. I'm not comfortable with this "answer." The noise started too suddenly, and is loud enough that I'm concerned about doing damage to my car as I drive. And the noise doesn't sound like a rattle to me.
What could the noise possibly be? The car is a 2003 Subaru Forester with just over 100K miles on it. Should I get a second opinion?
Related question: The Meineke mechanic also found and showed me that the strut on one of my back wheels is in fairly bad shape. Its complement is fine but their policy is to replace struts in pairs only. That would be a bill of about $600. I really want to avoid that kind of expense, but what could the consequences be?
