Furthermore

​The S&S Grand National Slip-On Mufflers are a high-performance aftermarket exhaust upgrade designed to fit the unique and aggressive aesthetic of the 2018 Harley-Davidson Fat Bob (FXFB). As a brand with a legendary heritage in racing and performance, S&S Cycle engineers their products to unlock the full potential of the Milwaukee-Eight engine. These slip-ons are the perfect choice for riders who want to dramatically improve the sound and performance of their motorcycle while retaining its distinctive factory 2-1-2 exhaust header configuration. The “Grand National” designation signifies a race-inspired, yet refined design that is built for both performance and sophisticated style.

In addition

Aesthetically, the mufflers feature a classic, clean, and minimalist design with a distinctive, machined billet end cap that gives the bike a robust and powerful look. The exhaust maintains the Fat Bob’s aggressive, high-mounted exhaust layout, but elevates the style with S&S’s signature craftsmanship. These mufflers are available in a durable chrome or a sleek black ceramic finish, providing excellent resistance to heat discoloration and corrosion.

In terms of performance, the mufflers are engineered to improve exhaust gas flow and reduce backpressure. This translates to a noticeable increase in horsepower and torque throughout the entire RPM range, giving the motorcycle a more responsive and exhilarating feel on the road. The sound produced is a deep, aggressive, and authoritative rumble that is a significant improvement over the factory exhaust. As a slip-on system, installation is remarkably straightforward.
