It's hit or miss, but have heard of shops that can't weld SS. It has to do with the equipment and materials they have.

My local muffler shop was able to weld onto the SS FI exhaust system I have.

Added 28" branch pipes 2 1/4" diameter pipes just before the mufflers and it has quieted down the drone a good amount. I still get drone right at 2K rpm but higher up it a lot better.

Also added a foam ensolite in the trunk to help.

Problem is now I hear some rattling from something that's loose near the muffler.
