Here's a good mod to keep the pipes from moving inward towards the body:
Rubber side pipe hangers for a BDR

The previous owner of mine did a similar mod to keep them more rigid. These were really helpful back when the cars came with slip-fit side pipe connections instead of header flanges.

Unfortunately these suggestion weren’t the culprit. Since backdraft is closed I made video to send to them to see what the noise maybe. It seems to me it is right where the 4 pipes go into 1 and right by the bolt foe what looks to be location where exhaust sensor will go.
