Look like Flowmaster clones.

Welded ends... Must be an upscale version. Most of the mufflers nowadays are just rolled and crimped

They look like stainless steel and my bet would be that they are Flow Master! Not clones.

It would be difficult to know what brand without seeing the inside

yes they are flowaster knock offs. too bad they dont show the innards. probably not the SS ones.

sounds like Santa's workshop...
