2010 Mazda5 air rushing sound?

I have a 2010 Mazda 5 with 260k+ miles on it, it's been a little loud for the past few months (Indicating a damaged exhaust) but it recently started making a rushing air sound when revving the engine. It's almost like either you turned the air conditioner up full blast, just the sound of rushing air. I will try checking it myself later today, but want to know if there are any specific things I should look for to find the source of the problem. Any help would be appreciated!
