Upgrade the sound and performance of your Harley-Davidson Softail Fat Bob with Cobra El Diablo 4-Inch Slip-On Mufflers, manufacturer part number 6046B. These black mufflers feature a distinctive cone-shaped megaphone body with a black beveled tip, combining a custom appearance with the aggressive exhaust note expected from Cobra. The El Diablo design draws inspiration from Cobra’s El Diablo 2-into-1 exhaust system and is engineered specifically for select 2018–2023 Harley-Davidson FXFB and FXFBS models.
Inside, a spun-louvered core helps deliver the bark, throttle response, and horsepower increase associated with Cobra performance exhaust products. The megaphone muffler body is manufactured in-house and transitions from a 2.75-inch inlet to a 4-inch rear outlet for a broad, muscular profile. A machined beveled tip complements the tapered body, while an etched Cobra logo adds a refined finishing detail.
