Whether you’re rolling up to a meet or downshifting through a tunnel, this setup will have people turning heads and asking what’s under the hood. And when the 2-step hits Instant chaos.

  CRACKLE POPS / OVERRUN

Let it snap, crackle, and BANG!
Our Crackle & Pop feature (aka overrun) lights up your exhaust with wild sounds every time you let off the throttle. Whether you're ripping through the gears or just free-revving in neutral, this map gives you that aggressive "pop-pop-pop" that makes people turn around and stare.

Got a downpipe or aftermarket exhaust? Expect full-blown firecracker vibes. Still stock? You’ll still hear it—just a little more subtle. Either way, it’s the kind of sound that puts a smirk on your face every single time.

Choose your level:
Low / Medium / Full Flame Mode (when paired with the right hardware)
