VANCE & HINES - Hi-Output Slip-Ons - Softail FXFB/S 18-23 Black

Enhance the ultra-radical style of your machine with the Vance & Hines Hi-Output slip-on mufflers. Specifically designed to match the muscular lines of the Fat Bob, these mufflers feature a stepped, stacked, and truncated design that instantly accentuates the stocky, urban look of this iconic model.

Hot-Rod Style and Performance Optimization

The stepped design of the Hi-Output range is not just aesthetic: it is technically calibrated to improve the engine's volumetric efficiency. By optimizing exhaust gas extraction, these slip-ons help to unleash the maximum power of your Milwaukee-Eight engine. While they perfectly complement stock engines, they also ideally meet the requirements of modified engines (Stage 1 and above).

A Heavy and Aggressive Sound Identity

True to the American brand's reputation, these mufflers radically transform the Fat Bob's acoustic signature. They deliver a deep, heavy, and particularly throaty rumble at low RPMs, which transforms into a powerful and ultra-aggressive roar during hard accelerations, without ever becoming shrill.

Premium Finishes and Robustness

Made from high-quality steel, these mufflers receive a high-temperature textured matte black ceramic coating of racing quality. This treatment ensures perfect resistance to thermal stress and prevents any whitening or discoloration over time. Attention to detail extends to the end of the pipes with superb laser-engraved and riveted aluminum badges, offering an impeccable high-end finish.

Chassis Compatibility

Compatible models (Softail M8 Fat Bob 2018-2023): Fat Bob 107 (FXFB) from 2018 to 2020, Fat Bob 114 (FXFBS) from 2018 to 2023.

🔧 Installation Notes and Technical Specifications

• Ultra-fast Slip-On Mounting: These mufflers slide directly onto your original headers. Installation is simple, quick, and requires no structural modification to your exhaust system.

• Injection Specificity (European Euro 5 Models): For recent European versions from 2021 onwards, electronic configuration via an injection management unit is highly recommended. This allows for proper deactivation of secondary downstream oxygen sensors (lambda probes) to ensure an optimal carburetion cycle and avoid any check engine light.
