  • milltek 100 cell cat?

    am i rite in saying there is a milltek 100 cell cat available, is it possible to swap my 200 cell one for a 100 cell one just like that or will it not fit into the system

    No, not yet. THe 100 cell version isn't released yet and my never be, the Astra is quite susceptable to O2 readings and the 100 cell maybe a bit too far.

          The 100 cell cat has 100 less cells than the 200 cell cat

          Always one aint there

          I have no idea i know that the 100 cell cat is smaller due to it having less 'STUFF' in it

            The cells are measured in cpi which is cells per square inch. So a 100 cpi cat has 100 cels per square inch inside and a 200 cpi has 200 cells per square inch inside. In otherwords the inner filter (the cat) is a tighter nit in the 200 cell cat than in the 100 cell cat! Hope that helps! :P

                As Zoomboy said it's to do with cpi ( or basically density). The big advantage of a lower cpi cat is the reduction in flow restriction. The lower the cpi and less restriction the cat causes - therefore better flowing system, more power :wink: Leymans terms

                    Indeed the ultimate is no cat - but as said it's illegal now so wouldn' t recommend, anyhow with the increase in flow you'd probably break any cat you had anyway
