The companies

Dr. Jekill & Mr. Hyde

The Jekill and Hyde Company® is one of the leading manufacturers of electronically adjustable exhaust systems. With a simple push of a button, you choose the gentle Dr. Jekill mode or let the unmistakable Mr. Hyde off the leash.


The creative and innovative exhaust forge from the steel city of Linz on the Danube in Austria has been producing exceptional exhaust systems in hand made to the highest quality and standard for over 20 years. In doing so, responding to individual customer requests, such as surface finishes in high-gloss polished, showchrome, satin, cast finish, outline or gilding, is just one of the special strengths.

The vision

A unique exhaust system for all Harley-Davidson® Softail and Breakout's from year of construction 2011 to 2016 with the best products of the two manufacturers and 100% legality!

From The Jekill and Hyde Company®:
Electronically adjustable mufflers with three different performance modes in two versions - Shorty and Jekill Bomb in chrome and black finishes, plus five different end caps in chrome, black, aluminum and polished RVS finishes.

From BSL® Products:
Five models of headers with two different designs on heat shields - Smooth and Hole - and in two finishes: chrome and black. BSL® uses annealed stainless steel tubes with 1.5 mm wall thickness and 1 ¾ inch connection. This results in 8% more volume and thus more draft with maximum exhaust flow. The interference tube for more power is included.
