Default Check for clearance around the center body cross brace.

However, I can hear a " metal sounds" from the muffler when I stop the car at the red light, sometimes on the road, but not too loud.

The sounds disappear after a while the car running. I am not sure if that is because the exhaust is still new and in " break in " condition?

The exhaust I bought is brand new, which no damage.

Will the sounds disappear after the break in time? Or I am the only one who have this problem?
I had a similar issue but not the same exhaust. AAM S-Line here. For me this turned out to be a clearance issue around the cross brace in the center of the underbody. A welded stainless piece of bar stock that secures the dual pipes together was vibrating against the brace. I grabbed some spare silicone tubing and wrapped the small stainless bar with it and secured it. My metallic noise abated.

You might check there. Hope this helps.
