SOLD...

I installed an M&K on my 69 3.0 so this muffler is available. I have no idea how to tell who the manufacturer is . Ideas where mftrg stampings are? Straps are included. BTW, I do not think this is a stainless muffler as mentioned in the title since I see evidence of surface rust on some edges. Nothing serious, just some rust color and I believe that stainless doesn't turn this color., correct?
