Question For those with SMB metallic substrates: Do you get creep at all?
I'm sure by the time you decide to upgrade your stock cats, most of you probably have a downpipe and a cat-back. So, for those of you who have SMB metallic substrates, do you get creep at all on the stock wastegate port size?

I don't have an SMB, but i do have a Random Technologies metal substrate cat in my mid pipe. It helped tremendously in controlling boost and eliminating creep.

Off topic, but did you keep your air pump bung on there?
