Hi! I have a Toyota Sienna that has begun running loud, especially around 40-50 mph. It doesn't feel like it is hesitating or slipping. Any ideas what this could be? It only has about 70K miles on it and has had proper preventative maintenance. Also, there do not appear to be any issues with the muffler system.

Thanks

It may have a collapsed baffle in a muffler, the muffler will look ok from the out side, normally you can tell by giving the muffler a thump with your hand (cold) and if it rattles you have a problem there.
