This is true, but it works both ways. Say you're cruising at 4000RPM and you slightly increase the amount of throttle being used. The sound it makes right away at 4000RPM is different than if you pushed the pedal all the way down right away. Or if that doesn't make sense, say you're just cruising at 4000RPM, compare that sound and the amount of exhaust coming out, to that of say 2000RPM with the pedal all the way down.... maybe?
It makes so much sense in my head, but when I go to type it...it comes out completely different, haha
