My muffler had to be replaced due to a bracket hanger that broke off from the Exhaust System Hanger. Instead of welding a new bracket hanger I had to buy a new muffler assembly.

My question is, the person who installed the assembly said the part was not the correct pipe. He also said it would be alright. Should I be worried about this?

The picture uploaded shows the type of part I had installed, not intending this is the correct part installed.

If it is not leaking and fits, I would not be concerned, although I would have probably welded a new hanger on.

If you notice any performance loss, or driveability problems, then I would look at getting the right part.

I did not see a picture?

Does the configuration of the muffler, if it is wrong, degrade the cars performance?

I do have a hum noise, not normal, when accelerating.

Unless the muffler is way too small, I would not expect any loss of performance. Mufflers have a flow, that is, an "in" and an "out", so unless it was installed backwards, I would not be concerned.

You can have a backpressure test performed if you think it has lost some power.

The hum could be a vibration in the exhaust, so I would make sure the hangers are in the proper places, so the exhaust is not rubbing against anything.
