My baffle was found to be scorched on my RMD 8555 that had replaced the original RML. Reace found it when I had him pull it a year later(5/16) as I didn't like how it had been trimmed out in front. I posted a picture. Can't seem to find it easily either.
The cause was due to improper installation of baffle as the RMD is a little deeper than RML.
