Hey all, I stumbled across a ceramic cat the is the same dimensions as my steel cat. It got my gears turning because my steel combuster has very small holes and likes to plug up quickly with powdery fly ash. This ceramic aftermarket version has bigger holes for the gasses to pass through so it seems it would be less prone to plugging up. Are the ceramic cats inferior in any way? Would I be doing a bad thing by putting a different style of cat than factory in my stove?
