Exhaust Rattle Due To Clamp Failure

An unexpected failure indeed! The mid-pipe clamp bolt corroded, the clamps collapsed and the bottom clamp departed! Sending the bottom section into traffic behind me (sorry NH drivers!) and the top half rattled on the pipe for the next week before I could get under there to figure out the noise source during start-up.

A rubber mallet tap found it quickly. Placed an order, installed it while coating threads with Wurth CU 800 copper paste and that was it.
