Aftermarket catalytic converters?

Try woodsman parts plus .com They have them for 113 bucks for my old stove They are a mom and pop shop . nice people

Check out www.condar.com They have replacements in either the ceramic or steel cats. Or check out www.stovecombustors.com These are cheaper but have heard they tend to clog easier than the honey combed style.

I have an aftermarket combuster from my old Defiant. It’s 2.5"W x 13"L x 1.25"D

It’s designed to fit the Vermont Castings Defiant Encore later models (and probably earlier). Here is the page on it:

I’ll sell it for $50 plus postage to you. If you are not interested then I’ll sell it to the first person who PM’s me about it.

It was used in a couple burning sessions and then taken out when the replacement OEM module arrived under warranty. It’s in good used condition. There was an expanding gasket that came attached around the edge of the combustor. It fell off after the unit was taken out (it is designed to go 2X in size to seal around the edges and becomes very brittle). You can buy it cheaply from Condar to re-apply it to this element:
