Dealer work, catless + tuned

Hey folks,

I'll be getting the 24k service done soon and I was curious what my options are. I have a Cobb AP and a completely catless turbo back exhaust. If I unmarry the AP for the service, I'll get a check engine light. I'm worried about leaving it married to defeat the CEL.

What are my options? Should I get one of those cat delete things that plug into the ECU? Seems like a step price to pay for 1 day out of the year..

Anyone in a similar situation? What did you do?

(BTW I know the CEL doesn't show up right away, but who knows what they do behind closed doors...)
