You have probably heard the pop & bang even on some cars that haven’t been modded. They are of far lower intensity and usually found only on sports cars, but the possibility of aftermarket mods which can bring the massive sound to almost any car has made it incredibly popular in the recent years. 


What is a pop and bang remap?

The pops, bangs and crackle mod is also called exhaust crackle deceleration, exhaust popping, burble, car backfire, crackle map, anti-lag system (ALS) or deceleration map. It results in those beastly bangs and healthy gurgles from the exhaust when the accelerator pedal is released.


It is as simple as that and absolutely beautiful.
