Hi everyone,
i got an Armytrix valvetronic exhaust system installed on my 2015 BMW 435i Xdrive and i'm afraid it is not working. I did NOT see any sound difference from stock! The valve closes and opens as i press the armytrix key but the sound still doesn't change. It's as quiet as it can be.

I had the exhaust installed by a professional mechanic.

Also, when i try to connect my phone to the Armytrix OBD2 dongle it tells me that the app is not supported. I tried over 15 times, and i can't connect.

I really don't know whats going on. I've been saving for over a year to be able to buy this exhaust and now this happens? I'm very disappointed.

I e-mailed Armytrix, no answer.
Thank you in advance guys.
