A Black Zero Labs appPlanned

Tonehouse Custom exhaust

Hear your exhaust before it exists.

Tonehouse is a planned app for designing a custom exhaust for your own car and hearing a preview of how it will sound before anything is made.

When the design sounds right, the plan is to have it built by a partner fabricator in the material you choose.

How it is meant to work

From the firing pulse
to the finished part.

Firing pulsesPipes, chambers and tipThe note

Bay 1The sound

Hear it
before it’s built.

The preview is planned to be generated from the design itself: the engine’s firing pattern sets the pulses, and every pipe, chamber and tip shapes them.

Change a part and the preview is meant to change with it.

Aim for the
sound you want.

Pitch, bass, rasp, drone and volume: describe the sound you’re after, and an assistant proposes the part changes that move toward it.

Previews will be labelled for what they are: an estimate, calibrated against real recordings as they become available.

Bay 3Built to order

From your design
to your car.

The intent is a design that fits your exact vehicle, built by a partner fabricator in stainless steel, titanium or another material you choose.

Fit and the noise limits where you live are planned to be shown before an order is placed.

Planned capabilities

Designed around the sound.

Parts list

  1. A preview you can hear

    A generated sound that follows every change to the design.

  2. Parts that shape the note

    Headers, pipes, resonators, mufflers, valves and tips, each changing the sound.

  3. Made for your car

    Designs planned around your exact vehicle.

  4. Built in your material

    Ordering through partner fabricators, in the material you choose.

  5. Your AI, through Lab Partner

    Proposes part changes toward the sound you describe, for you to review.

Works with

Designed to share one core.

Tonehouse is planned to work on its own, and to share the suite’s engines for geometry, sound and drawing.

Questions

Tonehouse, answered.

Anything else? We'd love to hear from you.

Get in touch

Is Tonehouse available?

Not yet. Tonehouse is planned, and nothing can be downloaded or bought today. The waitlist hears first.

Will the preview sound exactly like the real exhaust?

No preview can promise that. Tonehouse is being designed to generate its sound from the design, to calibrate it against real recordings, and to say plainly how close each preview is expected to be.

Will my design be road-legal?

Noise and emissions rules differ by country and region. The plan is to show the limits that apply where you live before an order is placed; fitting and use stay the owner’s responsibility.

Can I use Tonehouse without the rest of the suite?

That is the intent. Like every Black Zero Labs app, Tonehouse is planned to work on its own, and points to the full suite for people who want more.
