Does anyone know how many cells each primary OEM cat has and how many each secondary cat has?

Thanks

From my understanding the primaries are 400cpi while the secondaries are 200cpi.

That's what I thought as well. When I smashed my secondary cats out, it certainly looked like the they had a much more open honeycomb than the primaries.

thanks for the info gyz, so extracting primaries results in having an X pipe with HFC!!!
