Stock 335is exhaust HAS an X-PIPE Welded on from BMW also with a valve near the driver side muffler that triggers when you WOT but if you unplug the wire then it stays open. Not 100% sure what kind of exhaust the 335is has but its way louder and meaner than a normal 335i exhaust with X-pipe or straight-pipe mod. Dont want any arguement over what the 335is exhaust is but it sure is great! Wasn't louder enough for me so I went with Vanguard to get more performance and airflow.
