Im not an expert on Exhausts but i think it may be "After-fire" (Back-fire) just without the flames.
Or maybe a "by-pass Valve"

That's after-fire in the exhaust system. Which can happen for a couple of reasons.

> It can happen naturally, because exhaust gases are flammable at hire temperatures. If the metal of the exhaust pipe is hot enough it can re-ignite some of that mix and create a bang or crackle. You mostly see this in racing cars, when braking after a long straight.

> And on some modern sports cars, there's a tiny fuel injector fitted in the exhaust system to replicate that sound. When you shift gears in Sport + or a similar mode it'll release a tiny amount of fuel vapour and produce a crackle. Mercedes are particularly known for this.
