FAQ

Fitment

Will this fit my car?
We currently build controllers for BMW, Volkswagen, and Audi models with factory electronic exhaust valves, with more fitments on the way. Shop by vehicle to find your model, or get in touch if you don't see it listed yet.

Installation

Is installation permanent?
No. Every controller is plug-and-play — it connects in-line with your vehicle's factory wiring, so there's no cutting, splicing, or permanent modification. It can be removed at any time and your car goes straight back to stock. See our step-by-step install guide for the full process.

Will it trigger a check engine light or fault codes?
No. The controller doesn't interface with your ECU or engine tuning — it simply gives you manual control over the factory valve actuator.

Do I need a mechanic to install it?
Most customers fit it themselves with basic hand tools. If you'd rather not do it yourself, any auto electrician or performance workshop can install it quickly.

Orders & warranty

Does this affect my factory warranty?
Our controllers are designed to be fully reversible and don't modify your engine management. If you have concerns about how aftermarket accessories interact with your specific warranty, we'd recommend checking with your dealer.

What's covered if something goes wrong with my controller?
See our Shipping & Returns page for warranty and returns details.
