* Mid-Length 4.0-inch Muffler Bodies

* Classic Racing Nameplate

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 are running stock header pipes you will need # CG-C10365 (Muffler Gasket Kit). If you have aftermarket headers pipes, these don’t require gaskets.

* Fuel Mixture Calibration is Advised.

* Recommened Additional Purchase # PYO-SPAB Straight Pipes Adjustment System
