G20 M340 service issue

So i just got my 2020 M340 back from a regular service yesterday where they did have to fix an engine recall for my year. As soon as i got the car back i noticed the sound of my exhaust was a lot quieter than it was. Besides them resetting all my settings and having to fix that, which did include having to reset my sport individual settings back to sport plus. But even still in Sport mode i’m getting way less pops and way less gargle. I have the M Performance Exhaust on which even in comfort mode id get a nice gargle at really low rpms. Nothing now, it’s almost like i got the quieter hybrid 2021+ car back in return lol. Has anyone else experienced this after taking your car back for any kind of service? Is it possible for them to make the car any quieter?

The starter recall is a software i-level update, where rumor has it, updates from some of the older i-levels remove some of the pops/burbles compared to brand new.

In answer to another post, I took my 2020 M340i in this morning. Took less than two hours while I waited.
Car sounds the same.
