Car makes a loud roaring noise upon start...

What is your question?

It's real loud upon start up and idling. Continues throughout driving but not as loud. Seems loudest once you crank it up and during the first 2-3 gears. Almost sounds like a muffler, but not sure. It comes from the front and like I said...it's loud roaring sound. Any suggestions before I can afford taking to the shop??? Thanks.
