Stealth Pipes’ Derby Covers are CNC machined in the USA from aircraft-grade 6061 aluminum and built to deliver durability, clean style, and rider personalization. Available for both M8 Touring models (2015+) and Twin Cam Harleys (1999–2017 Dyna, 2007–2019 Softail, 2007–2015 Touring), these covers come in a raw machined finish and can be engraved with the design of your choice.
Designed for precise fitment with OEM specs, each Derby Cover uses stock style flat gaskets (not included) and stock hardware (Twin Cam) or requires flat style gaskets (M8). They’re the perfect blend of American made quality and custom ready design, built for riders who want to make their Harley stand out.
Muffler Sound Profiles Explained
Balanced
Balanced mufflers deliver a full exhaust note without excessive volume, making them ideal for riders who want strong sound presence without overwhelming noise.
Aggressive
Aggressive mufflers increase volume and bite, producing a raw, performance driven sound that stands out under throttle while still remaining rideable.
Extreme
Extreme mufflers are built for riders who want the loudest, most unapologetic sound possible. These options deliver an aggressive exhaust note designed to dominate attention.
