2012 3 Rear bumper cover swap help needed...
 

My son wants to swap out his 2012 3i touring hatchback's rear bumper cover (single exhaust) for a dual exhaust cover.. along with the exhaust. My question for the board is.. is this a straight up swap? Or are there any mods that have to be done for it to attach properly... My local dealership parts guy does not know... so I am asking the experts here.
Thank you for any help in determining this!

Nobody??

At indication on my mazda 3,2006 model dashboard
 

I noticed timely light indication "AT" from my car dashboard. I changed the gearbox still the AT sign still shows. Could it be a electrical problem or airflow meter issue?

FYI.. the single exhaust bumper cover swapped out perfectly with dual.. no issues..
Sorry Emmanual.. can't help you there..
