S&S - Diamondback 2-into-1 Exhaust - 17-25 Touring - Brushed Stainless or Black
Give your Harley Davidson a complete stainless steel exhaust system, designed to combine performance, reliability, and high-end style.
Equipped with heat shields on the manifold, it ensures better heat management while enhancing the system's durability.
Oversized primary tubes with progressive section optimize exhaust gas flow, thereby improving engine performance and responsiveness across the entire RPM range. The manifold length has been specifically designed to maximize the efficiency of M-Eight engines.
The 4" outer diameter (OD) stainless steel muffler ends before the rear axle, offering a shorter, aggressive line perfectly integrated into the bike's style.
This system includes four O2 sensor bungs, facilitating easy installation and precise air/fuel mixture control.
Thanks to computer-aided design and precision bending, this line ensures optimized ground clearance without compromising performance.
Manufactured in the USA, this system guarantees quality, robustness, and mechanical excellence.
