All cars 2012 and up have the identical valved exhaust. Only difference is the exhaust finisher shape. In 2011 only the s had a valved exhaust and the valve was located in a different location (behind the muffler) as opposed to on the driver's side of the muffler as it is on 12+ cars.
Slightly off-topic, but I think it's great that I can visit this forum every day and learn something new.
To amend what I posted, the MR.16 diagrams are for NA MTs from start of production to VIN BH_11177, so if the OP's NA falls within this range, it's likely the ECU won't support adding the solenoid, so no native Sport button control over the valve.
