its the diesel particulate filter, to get rid of it you take the sensor out of exhaust remove the exhaust amd get a turbo back from a previous model, then get a ppe or quadzilla tuner to clear check engine light. It will most likley void warranty but you can always put stock on to go the dealer, i did mine and saw a 4mpg increase in mileage.
