These days , 4.5 " seems to be the ideal muffler diameter for sound , power and looks . Firebrand has taken that formula one step further on the modern H-D touring machines with a highly tuned , louvered stainless steel baffle . But how do you tune a baffle , I hear you ask ? " Contrary to many people ' s assumptions , a baffle isn ' t just a tube with some holes - or at least it doesn ' t need to be . Firebrand ' s expertise is using the size and angle of the louvers , as well as their location within the muffler , as critical design variables 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 and a billet tip . Available for 1999 through 2022 H-D Touring bikes in Asphalt Black or show chrome . All Firebrand exhausts are made in the heartland of the US and available through HardDrive ."
