Mainly it’s in the tune. If I’m not mistaken, the ECU is Programmed to push extra fuel in the exhaust stroke in the piston and when the fuel hits the hot exhaust pipe it ignites and pops… Exhaust set ups help a bit also. The main drawback with it is that it will shorten the life of the catalytic converter and if it’s an aggressive crackle map, it can melt and destroy it fast. So some people replace it with straight test pipes.. which is illegal for road/passenger use in various countries
