Currently, all stock exhaust except for the mufflers. Now, I do have an Airaid CAI and BBK 73mm throttle body. So I am not sure if you are looking for a completely stock sound besides the mufflers because I believe the added airflow changes it a little. I can confirm this because when I had the car entirely stock, is buzzed like a bee. After I added the Airaid, the stock mufflers got a bit louder.
