How the hell they did it ? Looks like some sort of valve somewhere.

Also, the sound on cold starts is insanely beautiful, there definitely has to be some neat trick.

Anyone can share some knowledge on this ?

I remembered the review from evo

https://www.evo.co.uk/renault/megane/20697/new-renault-megane-rs-review-2018-hot-hatch-lives-up-to-expectations

In the Engine, transmission section is a paragraph that may explain things;

Quote:
At the other end of the car is a neat exhaust system that aims to blend refinement with a sporty soundtrack without resorting to complicated electrically actuated flaps. Instead there’s a cleverly designed back box that delivers a muted burble at idle, yet as engine speeds rise the change in pressure causes the gases to bypass the longer silencer tube and head straight for the exit pipe to create a louder straight-through set-up.


I'll find out for myself next week when I pick mine up Big Smile
