How to Make the Backfire Sound?

Install an anti-lag system; Modify the exhaust pipe, specially crafted exhaust pipes can even produce the same throttle roar as original models like Maserati and Jaguar. Press the accelerator to increase RPM, then release it, and the exhaust pipe will emit a popping sound - this backfire is the sound of the exhaust.
I love tinkering with car modifications, and to get that engine backfire sound, it mainly involves tuning the exhaust system and ECU settings. Install a high-performance exhaust valve, then adjust the car's computer to intentionally leave some unburned fuel when you let off the throttle. When you suddenly release the pedal after a hard acceleration, that leftover fuel ignites in the exhaust pipe, creating a loud 'pop' sound—super thrilling. However, this kind of mod costs a bit and might damage exhaust components, like frying the catalytic converter, so I recommend going to a professional shop instead of DIY. Safety is also crucial—backfire sounds are extremely loud in residential areas and might violate noise regulations, so testing on a track or open field is smarter. My own car has an aftermarket fuel injection program, and it works great, but I regularly check the engine condition to prevent issues.
As someone who frequently commutes by car, I've noticed that my small-displacement turbocharged car occasionally produces backfire sounds when releasing the throttle at high RPMs. The operation is simple: floor the accelerator to let the car surge, such as pulling to 4,000 RPM in second or third gear, then abruptly release the pedal, and you'll hear "pop pop" sounds. This isn't exclusive to modified cars; some factory settings tuned aggressively can produce this effect. But don't do this too often, as frequent backfires can increase exhaust pipe wear and may trigger the engine warning light, affecting longevity. For safety, avoid trying this on crowded roads to prevent startling others. I've tried gently pressing and releasing on the highway—the sound is quieter but still enjoyable. After all, driving safely and being environmentally friendly are more important, and maintaining regular vehicle checks is key.
