3. The metallic cores experience 15%-30% less pressure drop than a ceramic of the same size and cell density

4. They provide more cost effective canning methods

5. Reduction of overall size of packaging

6. Can be produced to weld directly in exhaust system

7. They have higher thermal shock resistance
