I don't notice any difference during other driving conditions. After another day of driving, I can clearly tell the difference between stock and the M Performance exhaust, but it's still pretty subtle considering the stock exhast already has a pretty nice sound to it. The "burble" sound is much more pronounced and makes a deep bass sound in the cabin with the windows are closed. Overall, I'm very happy with the result.

Sounds great. happy to hear you can def hear it with the windows closed.
In your opinion is it worth disengaging the exhaust valve?
Also, looking forward to a vid
