It comes with all necessary hardware, including new OEM-style mounting brackets, to make the installation process as smooth as possible. The system also includes a set of high-performance catalytic converters that meet EPA emissions requirements, making it a legal option for street use.

In addition to its performance benefits, the Brothers Racing MN/3SMN exhaust system also boasts a stylish design. The polished stainless steel finish of the exhaust headers and muffler not only look great but also protect against rust and corrosion. The system also comes with black heat shields to protect your legs from the exhaust heat.

Upgrading to the Brothers Racing MN/3SMN 2-into-1 Gen-II Exhaust System for your Harley-Davidson 2010-2013 Night Rod Special or Stock model is an excellent way to improve the performance and sound of your motorcycle while maintaining a legal and stylish appearance.
