Four exhaust setups
From factory quiet to straight pipe. Each one changes the tone, the rasp and the crackle.

Your car.
Any engine.
REVV reads your rpm over OBD-II and plays a real-time V8, V10 or V12 through your car's speakers.
Hear it
Seventeen engines. Zero recordings.
Every sound is synthesized live from firing order, headers and exhaust, so it follows each rpm without loops.
Rendered by the REVV sound engine: idle, a blip, a full rev to the limiter and a lift with crackles.
Plug in. Pair. Drive.

Plug in an OBD-II adapter

Pops on demand
One slider, from a gentle burble to a full flame show on every lift.
Rev matching
A calm 4,000 rpm in your car can be the redline of a V12.

Questions
Short answers here. Anything else, write to us from the support page.
Which adapter do I need?
An ELM327-compatible OBD-II adapter with Bluetooth LE, such as Vgate iCar Pro, vLinker MC+ or FS, Veepeak BLE or OBDLink CX. Adapters that only support classic Bluetooth can't connect to an iPhone.
Will it work with my car?
Almost every car sold since 2001 in Europe and 1996 in the US has an OBD-II port. REVV tries every bus protocol automatically and has a compatibility mode for picky engine computers.
Can the exhaust play from the rear speakers?
Phones send stereo over Bluetooth and CarPlay, so a car can only split left and right. Sound stage lets you choose what plays on each side.
Does it need the internet?
No. REVV works fully offline and sends nothing anywhere. There is no account, no ads and no tracking.
Is it safe to use while driving?
Set it up before you pull away and keep the volume low enough to hear traffic and sirens. Follow local laws on in-car audio.
