Could an aftermarket exhaust make a metal on metal noise?

Its the rearmost hanger, I had to cut about an inch off the end of the hanger so I could get the forward hangers on the rear section lined up and not have the hanger in the rear tapping the mount for the leaf spring right next to it. Itll make since once you look under there.
Luckily I caught it when I was installing so I hacked it off before finalizing the installation...

 

Switched to stock exhaust and itrs still making the weird noise.


Toyota has it and will do some tsbs.

 

Check your hangers, sometimes with the stock hangers ..it will cause the bpipe to rattle against objects or the subframe. You can buy extensions at your local auto parts store or muffler shop.
