PopBang & Burbless Software
The term "Popbang" or "Burbles" in the automotive world refers to popping or crackling coming from the exhaust system, especially in performance-oriented cars. This feature aims to make the sounds coming from the vehicle's exhaust system more dramatic and sporty. The "burble" effect usually occurs when reducing the vehicle's speed or releasing the accelerator pedal.
Software modifications to achieve this effect are called "Burble tune" or "Burble map". This type of software modification usually adjusts the vehicle's exhaust valve control and fuel injection, making popping sounds from the exhaust system more noticeable.
