How it works
Overrun sound depends on combustion strategy, exhaust design, temperature and operating conditions.

A vehicle-specific sound-character calibration request.
What changes?
A supported burble calibration changes exhaust sound during selected conditions. It can increase noise and thermal load on exhaust components.
Before you proceed
Confirm fuel type, catalyst or filter hardware and the requested operating mode. Flames are an illustration, not a promised result on every car.
Changes to emissions, diagnostics or noise-related functions may not be permitted for public-road use. Confirm the requirements for the intended vehicle and location with AutoScan before ordering.
