I'm on my second year with the replacement cat for my Kuma and I have been noticing a reduction in the cat temps once the bypass is engaged. I used to have temps ranging from 800 to 1000+. Lately I have been more around 700-800. My wood is very dry my chimney flue and cap are clean and the only thing I can come up with is the cat. I spoke with Kuma and they say after 6 months of burning you will see a reduction in cat performance. My last cat lasted 3 years before I needed to replace it. I do burn 24/7 for about 6 months of the year. If I do have to replace the cat it is not the end of the world. Kuma does offer a steel cat now the two I have used in the stove were ceramic. Does any of this sound right or am I doing something wrong.
