After replacing two steelcats prematurely, I can attest that the factory supplied steel combustor deforms after a relatively short period of use, and worsens with time. It severely inhibits draft flow, so much so as to cause back puffing and poor combustor performance. The Firecat ceramic completely cured mine. This problem isn't as noticeable with the smaller Federals, due to the firebox volume. The Firecat ceramic also provides and much more consistent and longer lasting temperature profile than the factory steel combustor. Hopes this helps someone else. I'm a ceramic convert. Nothing else will ever burn my smoke again. Thanks Firecat.Anonymoushttps://www.blogger.com/profile/00280889988782462613noreply@blogger.com
