I'm not sure about this , but how about installing a high flow cat were the resinator used to be, just after your turbo down pipe. I'm assuming that the resinator isn't thier anymore, so there should be space for one.

You may have to put the car back on the dyno to re-tune for the new exhaust change, but it might bring your emission levels down enough.

If you have any pics of your turbo set up, I'd like to see them, post a few. By the way, were at in Cali(Norcal or Socal) are you?
