test pipes barely give a gain in HP, so why do it?

You understand this code is part of a service bulletin, right? I recently had this code pop up on me recently, and when I took a trip to the dealer, I showed them the service bulletin and they agreed to upgrade my ECU with new software. Eventhough my Max is a 2000, it was still covered under warranty (I have low mileage, BTW, too). Just something you might want to look into if you already haven't done so.
