2017+ Milwaukee Eight Touring - Developed Specifically for the M8 our Stepped Baffles Enhance the M8 sound and aggression as much as possible without detriment to engine.
Disclaimer: A stock engine tuner is sufficient for normal everyday street use, if the only engine/intake/fuel system modification you have done is your Forsch Mufflers! However an Engine Tuner is recomended (along with high flow intake) to fully apreciate these pipes, and if any other modications have been made. Please note as with a stock / modified engine/exhaust, Damage wear & tear may occur faster than normal by practicing agressive riding such as applying instant full throttle at low RPM's! - read the HD manual - they don't like it when riders crank the throttle in a higher gear at low RPM vs gearing down and increasing, increasing RPM and reducing engine loads - if you pound it it all the time it will break, if you find you are always on the throttle - it could be time for Cams, Compression Increase, Bore kit etc.
