Dr. Jekill & Mr. Hyde

Sound-Adjustable 2-into-1 for Indian Chief Models

Dr. Jekill & Mr. Hyde, the Netherlands based electronically adjustable exhaust system manufacturer with full European type approval, has previewed a prototype 2-into-1 exhaust concept that will go into production soon for the Indian Chief.

J&H celebrated its 25th anniversary earlier this year, and now have a Jekill & Hyde distribution operation out of Henderson, North Carolina.

Its 'secret sauce' is a handlebar switch that operates an exhaust valve to cycle through three different sound modes and personalities on-the-fly. There is a modest, calm, 'Jekill' mode, the mid-range 'Dynamic' mode and the "wake up the dead" (well, not quite!) 'Mr. Hyde' mode. 

By a simple push of the button, a valve inside the muffler closes, opens halfway or opens fully to give the exhaust more power and performance. You can choose which to use, based on the circumstances through which you are riding - and the really neat part of the deal? 

These systems are street legal in Europe and are backed by a four-year warranty. The software is programmed to close the valve automatically when the parameters set by law and legislation are reached. 

Seen here, the system is in the final stages of pre-production prototyping for Indian Chief, Chief Bobber, Sport Chief and Super Chief.
