exhaust flap open/ close sound

hello,
are you supposed to be hearing the exhaust flap open and close when the engine is well warmed up?

Just today when I was parking in P4 condo parking lot, I had my Windows rolled all the way down and noticed the flap close whenever I let go of the gas and open whenever I put foot on the gas. couldn't have been doing more than 5kmph. it's this normal? it's like a clicking "ptchh" sound.

Thanks

Yep, completely normal and it is surprisingly pronounced isn't it!
