I uninstalled my bluetooth exhaust.
The dreaded separation of the catalytic converter seam on drivers side.
Got the TIG welder out and made it right.
caught it before it completely separated.So was able to run all the way around converter & added some extra weld at the bottom.
It should be good for another 100k.

So if yours sounds like an Evinrude in a bathtub or get O2 sensor codes, take a second to check and fix your cats.
