I recently had a new flex pipe installed and the car still gets Loud when I get up to 30-40 mph. I had them check to see if the exhaust pipes were sealed to the engine properly and they said yes. Could this be my engine and maybe needs a tuneup or a resetting of the timing? or maybe the converter is bad?..I think there is two of them..there are two pipes going to the engine.

Have you checked the flex pipe section under the engine, and the gasket between the manifold and cat/flex pipe section? Those are two places they usually start to leak from either a blown gasket, or the flex section rusts out under the protective covering.
your going to have to be more specific but there is a such thing as a flex pipe its rite under where the driver seat is under the car it connects to the exhaust they usually go back and the car gets really noisy if you look under the car they look like a pipe thats weaved metal like a basket but its a flex pipe.
