Can’t almost any car be tuned to burble or not burble? And don’t the super cars burble due to the way they are tuned (in other words, intentionally)? If so, what makes a burble “natural?” Are folks just referring to how much burble you have and criticizing cars with “too much?”

Natural: C63 is a larger v8 when ever you put an open exhuast on a larger high compression v8 on decel are hearinging the motor engine braking which causes grumbles and pops nautrally just from design of the motor.

Articifal: hanging injectors open for fuel that is un burnt running pass ther valves to the exhuast which then explodes causing pops and banks or flames.
