Most exhaust valve controllers cost somewhere between $150 and $580. Here's what moves the price, what should be in the box, the costs people forget, and how it compares with the other ways to get more sound.
Key takeaways
- Most exhaust valve controllers cost roughly $150 to $580 (USD). Exotics and more complex kits sit at the top of that range.
- The price moves with your car, how many valves it has, how the controller installs and what features it has.
- Budget for fitting. A wired kit can mean a workshop visit and time on a hoist.
- 11MODE is around US$300 for most cars and around US$430 for exotics, with US tariffs included and free worldwide shipping.
- Next to a $1,000 to $3,000+ fitted catback, a controller is usually a fraction of the spend.
- The cheapest controller isn't automatically the best value. Fitment, error codes and reversibility matter more.
01The short answer
An exhaust valve controller typically costs between $150 and $580 (USD), depending on your car, how many valves it has, and how the controller installs.
11MODE sits at around US$300 for most cars and around US$430 for exotics, with US tariffs included and free worldwide shipping.
Full disclosure: 11MODE makes controllers, so this guide has a horse in the race. That's why it covers what to check beyond the price tag, whichever brand you buy. Read it, sanity check it, and compare for your own car.
02What moves the price
- Your car. Kits for traditional performance cars cost less than kits for exotics. 11MODE prices exotic fitments like Lamborghini, McLaren and Ferrari on a separate tier.
- How many valves it has. Some cars run one valve, some run two. Some controllers differ in price for single or dual valve kits.
- How it installs. Most controllers are wired: you plug connectors into the factory harness and the valve actuator, route cables and mount a control box. A wireless controller like 11MODE skips the cables and the box, and plugs straight onto the valve actuator.
- Features. Extra drive modes, app control, memory functions and spare remotes all show up in the price. 11MODE has a memory function that remembers your last setting, ON or OFF, the next time you start the car.
- Where it ships from. Shipping, import duties and tariffs can add additional costs. Check whether they're included before you compare sticker prices.
03What should be in the box
Whatever brand you buy, check exactly what the kit includes for your car before you pay. A typical wired kit includes the controller made up of the connectors, wiring harness and control box, and a remote or switch.
The 11MODE kit is simpler, because there's less to fit:
- The controller, or two controllers for cars with two exhaust valves.
- One remote that works straight out of the box, no need to pair. Extra remotes can be added to an order.
- The memory function, built in.
A plug and play device that intercepts the signal to your factory electric exhaust valves and lets you override it, so you can hold the valves open on demand and then hand control back to normal factory behaviour. It allows for maximum exhaust flow for the most sound from the exhaust.
04The costs people forget
- Fitting. As with all car mods, professional installation is always recommended. A wired kit with cables to route and a box to mount takes longer. A wireless controller is a much shorter job. See the install page for what's involved.
- Shipping, duties and tariffs. These vary by brand and country. 11MODE ships free worldwide, and US prices include tariffs.
- Extra remotes. For the spare set of keys.
- The cost of getting it wrong. A kit that doesn't suit your exact car is money wasted. Check fitment first.
05How the cost compares with other ways to get louder
A controller is usually the cheapest route that keeps quiet on demand. Rough guides in US dollars, which vary a lot by car, brand and labour:
| Route | Rough cost (USD) | Quiet on demand | Reversible |
|---|---|---|---|
| Valve controller | $150 to $580 | Yes, one button | Yes, unplug and remove |
| Bypass plug | $20 to $100 | No, locked open | Yes, but no control meanwhile |
| Tune or valve coding | Varies widely, often a few hundred | Depends on the coding | Not always cleanly |
| Catback exhaust | $1,000 to $3,000+ fitted | Only with controllable valves | Only if you keep the stock system |
| Full exhaust system | $1,500 to $4,000+, past $5,000 on exotics | Only with controllable valves | Only if you keep the stock system |
The bypass plug is cheaper, but it locks the valves open with no way back to quiet / return to factory. The full side by side is in controller vs catback vs bypass plug vs tune, and if you're weighing coding instead, see do you need a tune to open your exhaust valves.
06Is the cheapest controller the best value?
Not always. Before you compare prices, check that the controller does these things for your car:
- Fits your exact car. Make, model and year all matter. 11MODE covers 1,000+ make, model and year combinations across 25+ brands; check yours in the fitment finder.
- Throws no check engine light. A quality controller shouldn't trigger one.
- Hands control back to the car. OFF should return full factory behaviour. Some controllers can force the valves closed, but that carries risk, because a car may need them open under load.
- Comes off cleanly. No cutting, no software changes, nothing left behind.
- Works on your valves. Controllers suit petrol cars with factory electric exhaust valves. Vacuum systems and diesels are out. The help centre shows where the exhaust valves are located.
Compare what you'll actually pay, not the sticker. Add shipping and tariffs, then ask what the install process looks like.
Noise regulations vary by country and state, and these products are sold for off-road and track use, so check the rules where you drive before running your valves open on the street.
07Frequently asked questions
How much does an exhaust valve controller cost?
Most cost roughly $150 to $580 (USD), depending on your car, how many valves it has and how the controller installs.
How much does 11MODE cost?
Around US$300 for most cars and around US$430 for exotics, with US tariffs included and free worldwide shipping. Check the exact price for your car in the fitment finder.
Is a controller cheaper than a catback exhaust?
Usually by a long way. A controller is roughly $150 to $580, while a cat-back is often $1,000 to $3,000+ fitted. A catback changes the maximum volume; a controller lets you keep your car's own maximum loud setting on demand.
Is a controller cheaper than a tune?
A custom tune with valves mapped to the engine and modes is more costly. A simple valve coding can be less than a controller but is more difficult to revert to factory. A controller changes no software, lets you easily revert to normal and comes off in minutes.
08The bottom line
Most drivers will pay between $150 and $580 for a controller, a fraction of a new exhaust for a sound upgrade. Add up the real cost, check the fit, and if your car has the valves, check your car and turn it to 11.
