Firebrand Monarch 4.5-inch Slip-ons for H-D Touring Models 

Slip-ons with highly tuned, louvered, stainless steel baffles.

4.5 inches seems to be the ideal muffler diameter for sound, power and looks. Firebrand has taken that formula one step further on the modern Harley-Davidson (HD) touring machines with a highly tuned, louvered, stainless steel baffle. How do you tune a baffle? Isn’t it just a tube with some holes in it? This is where Firebrand’s expertise comes into play.

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 new Monarch Slip-on from Firebrand does exactly that and finishes the muffler off with a durable and perfectly matched coating as well as a billet tip. Available for 1999 through 2022 HD touring bikes in Asphalt Black or show chrome.

All Firebrand exhausts are made in the heartland of the U.S. and available at your local HardDrive dealer, or check them out at https://firebrandmotorcycle.com
