Just a guess but it sounds like it's time for a new belt. Make sure the belt tensioner is not frozen also.

NEED TO TAKE VECHICLE TO MUFFLER SHOP LET THEM FIX RUST PIPE WITH A NEW PIPE.LET MUFFLER SHOP FIX BECAUSE THEY CAN WELD JOINT SEAL BOTH NEW EXHAUST PIPE AND NEW MUFFLER SO YOU WONT GET CARBON MONOXIDE POISON LET MUFFLER SHOP CHECK ALL THE EXHAUST SYSTEM BECAUSE THE WHOLE SYSTEM COULD BE RUSTED DROP DOWN WHILE DRIVING YOU PROBABLY NEED NEW EXHAUST PIPE HANGERS.

Probably corrosion inside destroying the baffles and letting the wadding to break up. Sorry new is the answer.

Call your local muffler shop.

KNOWN CONCERN IS FRT AND OR REAR SWAYBAR BUSHING,, BUT FRT STUTS AND REAR SHOCKS CAN MAKE A SUMULAR NOISE..

If the noise sounds like your muffler, but isn't coming from the area of your muffler, then you have an exhaust leak upstream from the muffler.

From the front of your muffler, follow the tubing forward to the catalytic converter, then forward to the engine exhaust manifold.

If you start with the car sitting for a few hours to make sure it's cold, you can use your hand to feel for blowing leaks while the engine is running, but chances are you'll be able to hear it. be careful of the catalytic converter itself, as it heats up fast, so check that first.

Once you've found the leak, the fix depends on the emissions laws in your state. If you have none, and the leak is in the middle of the pipe, you can buy pipe patchers (metal preferred) through auto parts stores or catalogs/websites. If you have strict emissions laws, or the leak is at the junction of the catalytic converter and pipe, you'll need to replace the failing part.

Leave the cat there. Just add a length of pipe and add a muffler (just get a cheap turbo for $20 bucks at a parts store). Clamp it all together and go. Should be fine.
