G63 AMG Brabus Exhaust valve actuator operation
I have a 2023 G63 AMG. Love the car so far but exhaust note was a bit quieter than I was expecting.
So I ordered the Brabus exhaust and then got it installed by a reputable master since the retailer of Brabus in my city did not offer installation and authorized dealer did not want to install it. Don't get me wrong car sounds like roaring tiger now and pops and bangs are much more noticeable in sport mode.
But i feel like master did not install the valve actuator correctly. First of all when i pressed the exhaust button on my car the valve used to make a mechanical noise like it is tightening. With new exhaust there is difference in exhaust sound but no such noise when exhaust button is pressed.
Also, i have recognized that even in silent mode both of the exhaust tips still have air coming out of them.
I think flaps don't fully close in comfort mode.
So what do you guys think? Can anyone with OEM exhaust confirm that both exhaust tips should have air flow in silent mode? And do you guys think actuator should make a noise when opening and closing?
Thanks in advance.
