Monarch 4.5″ mufflers utilize a louvered stainless steel baffle to insure a long service life and agressive sound, we then finish the business ends with a classic aluminum end cap for a distinctive crown finish and a subtle Firebrand logo treatment.
Tech Tips:-
* Does NOT fit 2017up Trike models. The 2017-2020 Trike’s use 1995-2016 fitment Touring mufflers.
* In 2021, for International Models, Harley shrunk the header pipe where the mufflers clamp on & added a gasket. If you a re running stock header pipes you will need # CG-C10365 (Muffler Gasket Kit). If you have aftermarket headers pipes, these dont require gaskets.
* Fuel Mixture Calibration is Advised.
* Recommened Additional Purchase # PYO-SPAB Straight Pipes Adjustment System
