MCJ ADJUSTABLE 2-IN-2 ROYAL 100 FAT BOY SYSTEM FROM 2025

2 products

Category dedicated to the MCJ 2-in-1 Royal 100 exhaust system, specifically designed for the Harley-Davidson Fat Boy from 2025 onwards. This exhaust set includes the headers and mufflers integrated into a compact twin-exit configuration.

About this category

Ideal for owners of modern Fat Boy models seeking to optimise gas flow and reduce weight compared to the original exhausts. The Royal 100 finish typically offers a polished or chrome-plated, corrosion-resistant appearance. Compatible with large-capacity Milwaukee Eight engines, this system improves throttle response and provides a sporty sound without sacrificing the torque characteristic of the Softail family. Essential spare parts for replacements or customisations.
