Car sounds like a lawn mower or go kart, maybe even motorcycle. I believe that the problem exists with in the Muffler, or its pipes connecting it to the engine. Any ideas?

Car is a '97 Alfa Romeo Italian Build and European Spec.

Car would have to be well secured and jacked up and when running chase down the suspect areas. Perhaps with like a good oven mit you could move around/tug on pipes and help find the problem. Mufflers can look good and have all kinds of rust inside that makes noise too,

It could also be the donut gasket where the tailpipe connects the exhaust manifold...

Good call Mopar, Thats what i was just about to write. You can locate this easily. Under your hood, while car is off, go look under the motor, for where your exhaust pipe looks like it joins to it. There should be 2 pipes depending. There will then be what looks like a plate where it joins. Inside that is your gasket. Once found. Start car and get someone to rev a little for you, see if thats where the noise is coming from. OR, have you changed your exhaust lately to a bigger one?

I have located the problem it was where the Muffler connected to the engine, someone had literally held this thing together with wire that was coming lose, I went to the local high school hobby shop and they replaced it with some new bolts and a seal, she sounds purdy now!

Amazing what the old "Coat Hangar and Duct Tape" tricks can pull. Did a shop do that to this car?

Well i bought it from a friend, he says he never noticed it before, he blames it on a shop he took it to.
