I activated sport mode then start the engine , but the exhaust sound is same as normal start sound?

 

I always start first, then activate Sport mode. It immediately puts the suspension in Sport mode and adjusts the shift points for a more aggressive driving mode. I can definitely hear the sound in exhaust (especially after a cold start) and mine is enhanced more as I installed secondary-cat-bypass pipes..

 

normal the mufflervalves are open when engine is off
