Why is my car's engine all of a sudden louder?

Question:
I was rushing to get to somewhere, driving really fast (accelerating fast, stopping going etc.), and all of a sudden after I got off of a ramp, the engine in my car started booming. It is now definitely louder then it was before, and this was a drastic, sudden change. It just booms, it's louder, lower and doesn't sound good. I drove back, it seems to be driving fine, but the engine is just extremely loud. I drive a '98 4Runner with around 170,000 miles on it.
