This is a warm start of my 2021 BMW M550i with the Remus Catback exhaust (with carbon tips). The exhaust gives a nice start-up note and usually gives some nice pops/burbles if in Sport or Sport Plus. This was started up in Sport Plus and just a few quick revs. It will sound the same if the car is in park or neutral and it sounds great. However, I'm not sure how nice the audio is makes it too well through the video.
