Seems like there’s always something but this one made me laugh a little. I switched to a metal under tray a while back which did not require the use of the rearmost mounting point. I was getting a wild vibration sound which I thought was a heatshield… and I did actually have one on the up pipe that had broken loose. After spot welding it back on I was still getting the same metal on metal vibration sound. Well, at least it’s fixed so I guess that puts me back at “Modify” in the cycle!
