These 4.5″ street compliant high-flow mufflers have been specifically tuned to deliver an aggressive exhaust note and improved performance. The straight-through perforated baffle reduces airflow restriction, and produces a rich exhaust note throughout the entire RPM range. You get a great performance, a powerful base rumble and a throaty tone while on the throttle, while maintaining a mellow note while cruising. Available in your choice of Brushed Satin Chrome or heat resistant Satin Black ceramic finish. Matching or contrasting end caps (sold separately) complete the custom look. Designed for International markets that require ECE-certified mufflers. Fits ’18-later FXFB and FXFBS models. Installation requires separate purchase of Muffler End Caps P/N 65100122 or 65100123.
