AMG exhaust snap, crackle, pop
I have an AMG GTC and I'm on the fence about the exhaust popping in Sport+ mode. I like a little of it but on aggressive downshifts it sounds like I'm dropping M80s. I think it's a shame there is not a middle ground setting where it doesn't sound contrived. Maybe that's just me?
Which leads me to questions about exhaust valve controllers. Can I assume that the popping is created by ECU adjustments that allows unburnt fuel into the exhaust system and has nothing to do with the valves?
So, if i purchase a valve controller, and I set it for 100% open in Sport rather than Sport+, will I get a nice, louder and beefier exhaust note without the fireworks?
Or, and I realize this is unlikely, is there a way to get a little popping and not a fourth of july celebration when I downshift? maybe a tune?

Pops usually help with anti-lag, so not necessarily for show only. The exhaust gases keep the turbines spinning. The rich mixture (that can produce pops) can also help with keeping temps down.
You can have a sport+ or race engine set (that would produce pops) and put the exhaust on silent. You could save it on Individual for easier access.
You'll still get pops, but they won't be as loud.

Create an I* / Individual Setting so that the exhaust is dialed down but you still have the engine, transmission, suspension to your preference

With your valve module, do you feel like the exhaust note (other than popping) is the same in sport and sport+ setting? Which module do you have?

What he said, honestly they should of just had the I-C, S+ and Race mode.
as far as popping goes, the more the merrier imho.

Mine doesn’t crackle so much
Pro tip: if you avoid the paddles most of the cracks don’t happen. Cold starts not included.

curious how the opf would sound but I had a buddy do some fly bys for me and launches and the car is seriously loud from the outside!
I would definitely recommend anyone on the fence about sound actually getting someone else to drive so they can hear in person from outside!
