HoLaS Dynamic Backfire is an advanced real-time exhaust flame system for BeamNG.drive.

Flames react dynamically to engine behavior, producing sharp backfire bursts, sustained flames, and ignition fireballs that move naturally from each exhaust outlet. Nearby vehicles, roads, walls, and surrounding surfaces are illuminated in real time, making nighttime driving especially immersive.

The included control app provides a polished Easy Mode for everyday players and a detailed Deep Mode for advanced customization.
