I removed the left exhaust today to check if the catalytic substrate/honeycomb had suffered any damage from the overheating it experienced.
A close examination of the catalyst didn�t reveal any visible damage. I then ran a test probe through a couple dozen of the catalyst/honeycomb cells to feel if there was any melting or fusing of the substrate at the exit end of the converter. No resistance or damage detected.
So I did a final cleanup of the overheated exhaust with �Blue Job� and replaced the exhaust back on my bike.
Later this Summer, once I�m sure the bike is continuing to run well and no longer overheating the catalyst with rich exhaust gas, I�ll replace the burnt exhaust pipe with an �As new� takeoff I purchased locally on Craigslist.
You can still see some overheating marks on the exhaust just below the rear mount; however, it looks much better.
