..... it's like WTF? it couldn't have been cheap muffler to purchase. Something broke loose inside. I have no idea what brand it is, but it's a stainless oval shape input and output from the same side, single exhaust.

If I can figure out the brand name, maybe there is a warranty? I guess too, I could have the end cut off, reweld the offending pipes inside and then reweld the end piece back on.
It makes the car sound like a 58 Ford Edsel everytime I hit a bump.
