Make sure the world knows you're riding a Harley! These 4" slip-on mufflers from Rinehart Racing deliver - this isn't no moped sound and great looks to boot. These mufflers were designed for Harley-Davidson motorcycles using the same race-proven baffle design as Rinehart Racing's True Dual Systems, meaning they're precision-machined in America to work with OE head pipes or match perfectly with their Slimline Dual Headers. If you're installing on catalyst-equipped OE pipes, there's no tuning needed or required. You can also mix and match your style, as these 4" slip-ons are available in chrome or black with matching or contrasting end caps. Your bike, your choice.
Note: For complete exhaust system, pair these mufflers with Rinehart Racing header pipes: 138-914 Chrome or 138-915 Black.
