6046B El Diablo 4" slip-on mufflers. Black

Cobra El Diablo 4-inch slip-on mufflers are the perfect first step for improving the performance and sound of your Fat Bob. Finished in a sleek matte black, these mufflers feature a spun-louvered core that allows the Milwaukee-Eight engine to breathe much more freely than the stock exhaust. The result is a deeper, more aggressive exhaust note and a noticeable boost in power. These mufflers are designed for a hassle-free installation, bolting directly onto your factory head pipes. Sold as a set, they fit 2018–2020 FXFB and FXFBS Softail Fat Bob models. For the best performance gains, we recommend pairing these with a high-flow air cleaner and a proper fuel tuner to optimize your bike's air-to-fuel ratio.
