Hi everyone, my automatic 1999 9-5 2.3 lpt makes a roaring sound b/w 30 and 40 mph. it didn't make that sound before. the noise doesn't seem to be coming from any side of the car in particular, and the muffler was replaced a few months ago. it really sounds more like a "wooooo" than a whine or a grind, and it's pretty loud - my passengers tend to (annoyingly) point it out. any ideas on what this sound could be? i can live with it but i don't want it to turn into something much worse if left unattended. thanks in advance for any help you guys can offer.
