Quality you can trust - Dr. Jekill & Mr. Hyde | The Exhaust does not only sound great, it’s also a very reliable and high quality product.

the valve the three personalities

Everything on your GS is adjustable, why not your exhaust? That’s what we thought. Therefore our exhaust systems embody three distinct personalities: the Dr. Jekill mode, the dynamic mode and the Mr. Hyde mode. By a simple push of a button a valve inside the muffler closes, opens or opens halfway, giving your exhaust more power and performance. You can choose per situation whether you want to ride in the Dr. Jekill mode, dynamic mode or Mr. Hyde mode. It’s up to you.
