The Stinger's Bi-Modal Exhaust System

combines premium hardware with intelligent electronics. Drivers are able to select from various driving modes such as eco, comfort & sport. The system controls sound output so that when in eco mode the exhaust is more or less silenced and when in sport mode you have noise from start to finish.

It's important that a car sounds as it looks although in some cases this isn't possible off the factory line. Kia approached Lumen to help develop a bi-modal exhaust system to enhance the driving experience of the Stinger. Lumen designed a bi-modal system with an integrated engine management system allowing intelligent control of the actuated exhaust valve.
