Main CAT cell rating???

[Ed30DSG]

Has anyone confirmed if this is actually a 400 cell by actually inspecting it?

I had the pre-cat material removed and that was 400 cell, but on 2 other cars the pre-cat and main cat have both been different types i.e. 400 cell and 200 cell.

Ta in advance.

OK, we cut the main cat out last week and it was indeed 400 cel - replaced it with a 200 cel Miltek sports cat

Hi,

This is something I've been considering doing myself.
Before you put the 200 cel miltek cat on did you notice a performance increase by just removing the precat material and did it make the cel light come on?
Did removing the precat material make it louder?

How does it go now with the miltek cat and the precat material removed?

Thanks

No cels by removing pre-cat material, but car deifinately spools up quicker now. Miltek sports cat has made it louder though, which I was hoping it wouldn't!
