Excuse my abhorrent Lateness to replying to this comment, but you do realize every Ferrari GT2 and E were all around 7000 RPM and below right? Heck, the 458 GTE in 2014 despite being a screamer had been one of the lowest in the 6000 RPM rev range. The reason the C8.R doesn't scream is purely the way the exhaust header/system is shaped. The sound doesn't bounce in a way to make a scream, rather you get the gruff sound you here irl. If you saw in some of it's early test videos, specifically the one at sebring, it was much closer to a Ferrari scream than it was now, cause back then GM had a different exhaust header/system they were testing with.
