WATCH THE MOD SHOWCASE

HoLaS Dynamic Backfire

Bring every exhaust to life.

Turn every lift-off, hard shift and high-rev run into a spectacle. HoLaS Dynamic Backfire brings responsive exhaust flames, rich smoke and optional afterfire sounds to BeamNG.drive. with the freedom to create anything from a restrained street-car look to an aggressive show build.

Flames respond to engine behavior, with sharp pops, connected bursts, sustained burning and detached lift-off fireballs. Watch nearby roads, walls and vehicles catch the glow, especially during nighttime driving.

New: Realistic + Smoke + Sound

Discover a dedicated style that brings flames, smoke and optional sound together. Keep your existing favorite styles, or give each vehicle a completely different personality.

• Flames with character. An anchored flame core, uneven bursts and lift-off fireballs create a varied exhaust display.
• Smoke that follows the action. Gentle exhaust smoke and stronger bang clouds spread, drift and respond to wind and vehicle movement.
• Your smoke, your look. Adjust the amount, density, spread, size and movement, with separate controls for exhaust smoke and bang smoke.
• Optional afterfire sounds. Add pops and bangs on compatible vehicles, keep the car’s own sounds, or choose the override option.
• Sound-driven bangs. Bring visible exhaust bursts together with the mod’s afterfire sounds.

Build Your Signature Look

Prefer subtle flashes from a road car? Long flames from a tuned build? Bright bursts for a nighttime meet? Choose a style, adjust the look and save it for that vehicle.

• Multiple flame styles for different tastes and builds.
• Customizable colors, size and intensity to suit your exhaust.
• Separate flame layers for finer control over the finished look.
• Adjustable burst and lift-off behavior to shape when the action happens.
• Live previews and exhaust-placement tools to help get everything looking right.
• Saved vehicle profiles so each build keeps its own settings.

Simple to Start. Plenty to Explore.
