Best Rally & Track Intercom Systems
An intercom system is only as good as the job you bought it for. A rally co-driver needs pace notes to cut through engine noise and stage bumps without the amplifier cutting out; a driver coach on a track day needs a clean, simple link into the car that doesn’t need fitting like a rally car’s wiring loom. Stilo and ZeroNoise both make good kit, but which one, and which model, depends on which of those two jobs you’re actually doing.
This is a buying comparison, not an explainer of how an intercom works. For that, see our existing post on ZeroNoise intercoms.
- Stilo's Raid amplifiers and ZeroNoise's Offroad amplifiers are the models each brand markets specifically for rally co-driver use; the standard versions are aimed more at circuit and track day communication.
- ZeroNoise's Pit-Link amplifier adds Bluetooth, useful for a driver coach or engineer talking to the driver from outside the car.
- Headsets and amplifiers are sold separately, and full face and open face helmets need different headset kits.

Rally co-driver comms versus track and coaching comms
A rally intercom has to carry a co-driver’s pace notes clearly at speed, over stage noise, with the amplifier and wiring able to take the vibration and knocks of a rally car. A track day or coaching setup is usually simpler: one or two people talking in a much quieter cabin, sometimes with a Bluetooth link out to someone standing at the side of the circuit. Buying the wrong type isn’t the end of the world, a rally amplifier will work fine on a track day, but you’ll often be paying for ruggedness you don’t need, or missing a Bluetooth feature that would make coaching easier.
For the co-driver's seat: rally amplifiers
The Stilo DG-10 Raid Digital Intercom at £450 and the ZeroNoise Fearless Offroad ClearVoice Intercom Amplifier at £542 are the models each brand sells specifically for rally and off-road use, as opposed to their standard circuit-focused amplifiers. The Stilo DG-20 Raid Digital Intercom Amplifier at £458 is the newer DG-20 platform in the same Raid form, if you want Stilo’s more recent electronics in a rally-specific unit.
For track days and coaching: standard and Bluetooth amplifiers
For a straightforward track day link between driver and passenger or instructor, the ZeroNoise Fury Digital Intercom Amplifier at £255 is the cheapest sensible entry point, and the Stilo DG-20 Digital Intercom at £392 is a step up if you want Stilo’s build. If you want a coach or engineer to talk to the driver from outside the car without holding a two-way radio, look at the ZeroNoise Pit-Link ClearVoice Bluetooth Amplifier at £532 or the Stilo DG-30 Evo Digital Intercom With Bluetooth at £1,088, which is the premium option in this list and adds Bluetooth on top of Stilo’s higher-spec amplifier electronics.
| System | Price | Best for |
|---|---|---|
| ZeroNoise Fury Digital Intercom Amplifier | £255 | Entry-level track day, driver to passenger or instructor |
| Stilo DG-20 Digital Intercom | £392 | Track and general circuit use |
| Stilo DG-10 Raid Digital Intercom | £450 | Rally co-driver communication |
| Stilo DG-20 Raid Digital Intercom Amplifier | £458 | Rally co-driver comms on the newer DG-20 platform |
| ZeroNoise Pit-Link ClearVoice Bluetooth Amplifier | £532 | Bluetooth link for a coach or engineer outside the car |
| ZeroNoise Fearless Offroad ClearVoice Intercom Amplifier | £542 | Rally and off-road co-driver communication |
| Stilo DG-30 Evo Digital Intercom With Bluetooth | £1,088 | Premium, Bluetooth-equipped, rally or track |

Headsets: match it to your helmet
An amplifier is only half the system. The ZeroNoise Full Face Helmet Intercom Headset at £63 is built for a full face helmet’s microphone and earpiece position, and there’s a separate open face version at the same price for open face and rally jet helmets. Both are a different product to a practice headset, which is meant for use without a helmet, for example when you’re checking a system on the bench before it goes in the car.
Getting it wired in
Beyond the amplifier and headset, most installations need connecting wiring and a power supply to tie the system into the car, for example the Stilo Amplifier Power Supply Complete With Camera & Radio Connecting Wire at £209 or the Stilo DG-30 Intercom Helmet Connecting Wiring at £115. These aren’t exciting purchases but they’re the difference between an intercom that works first time and one you’re chasing wiring gremlins on at a test day.
Common questions
What's the difference between a rally and a track day intercom setup?
Rally systems, usually the Raid or Offroad models from Stilo and ZeroNoise, are built and marketed specifically for co-driver pace note communication under vibration and noise. Track and coaching systems are usually the standard amplifier range, sometimes with Bluetooth for a link to someone outside the car.
What does the Bluetooth option actually give me?
It lets an amplifier connect wirelessly to a phone or radio, mainly useful for a driver coach or race engineer who wants to talk to the driver without being wired into the car themselves. ZeroNoise's Pit-Link and Stilo's DG-30 Evo both offer this.
Can I use the same headset in a full face and open face helmet?
No, full face and open face helmets need different headset kits because the microphone and earpiece positions differ. Check which you need before ordering.
Do I need a separate amplifier and headset, or do they come as a kit?
Amplifiers and headsets are generally sold separately so you can match the amplifier to your car's wiring and the headset to your helmet. Check the individual product pages for what's included.
Which system would you recommend for a first rally?
For a first season we'd usually point a co-driver at the Stilo DG-10 Raid or the ZeroNoise Fearless Offroad, both built for the job rather than a track day amplifier adapted to it.
I just want to talk to my instructor on a track day, what's the cheapest sensible option?
The ZeroNoise Fury Digital Intercom Amplifier at £255, plus a headset to match your helmet, is the simplest entry point we'd suggest.
What we would buy
If you’re kitting out a co-driver’s seat for real rally use, we’d put you in the Stilo DG-10 Raid or the ZeroNoise Fearless Offroad instead of a standard track amplifier adapted to the job, both are built and sold specifically for that use. For a track day car where you mainly want to talk to an instructor or your own passenger, the ZeroNoise Fury at £255 is the sensible starting point, and if you want a coach able to talk to you from outside the car without a radio in their hand, look at the ZeroNoise Pit-Link or the Stilo DG-30 Evo for the Bluetooth link.
Final thoughts
Wiring an intercom into a specific car or helmet setup is where most of the questions come in. Call 0115 9893488 and ask for Cameron if you want to check compatibility before you order.
