In the never-ending quest for the right exhaust muffler for your Harley-Davidson Touring Model, it seems the 4.5-inch muffler checks all the boxes in the sound, power and looks departments. Luckily for you Firebrand has taken that formula one step further on the modern H-D baggers with its new 4.5 Monarch Slip-On muffler, which features 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 gases 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-ons 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 exhaust are made in the heartland of the US and available at your local HardDrive dealer or check them out at https://firebrandmotorcycle.com
