Functionality
To make our electronically adjustable exhausts Euro 5 approved for 2 in 2 Softail models (except Fat Bob 114), we’ve developed a mandatory extender with a O2 sensor, placed between the body and the end cap. This solution (extender for the O2 sensor) is an important upgrade which guarantees Euro 5 compliance, and equally important, ensures the same exceptional sound and product quality you are used to from Dr. Jekill & Mr. Hyde.
