Made for Harley-Davidson touring models, the Firebrand Monarch 4.5-inch slip-on mufflers are finely tuned to enhance performance and produce an aggressive sound. The key to the Monarch’s performance is in the baffle.
These mufflers utilize a louvered stainless steel baffle. Firebrand explains that “the size and angle of the louvers as well as their location within the muffler are critical to capturing the exhaust gasses as they pass through. Too big and they slow velocity, too small and you risk a pitchy sounding muffler. Get it right, and your bike sounds and performs like a proper V-Twin should.”
The Firebrand Monarch 4.5-inch slip-ons are available in Chrome and Asphalt Black for $599.95 for Harley-Davidson tourers built from 1995-2022. Check out Firebrand’s website for more details and to listen to an audio recording of the mufflers.
