Hahaha I suppose that's one way of doing it!
pop pop bang pop I love the sound it makes! I guess it's something to do with excess fuel in the system burning up at a guess
This - but usually with a full stainless system. the low note pop bang pop rumble rumble sound is achieved by reving up to say 3000rpm and then just releasing all pedals. the car will win back down and burn excess fuel from full throttle
