4-1/2" Chrome MK45 Cutlass Performance Mufflers
Upgrade your motorcycle’s exhaust system with S&S Cycle MK45 Cutlass Performance Mufflers, designed to deliver a bold appearance and a deep, authoritative exhaust note. The chrome finish complements a wide range of custom and performance builds, while the Cutlass styling gives the rear of the motorcycle a distinctive, aggressive look. These mufflers are engineered for riders who want enhanced exhaust character without sacrificing practical street usability.
The stainless steel baffle helps provide durable internal support and consistent exhaust performance, while RaceTEX packing is designed to manage sound and withstand the demands of repeated riding. Together, these components produce a deep bass rumble throughout the RPM range, giving the motorcycle a strong presence during acceleration and a refined tone during normal cruising. The result is a performance-oriented sound that suits touring, cruising, and custom applications.
For additional sound control, each muffler includes a removable dB reducer, allowing riders to adjust the exhaust character to better suit their preferences and riding environment. The mufflers are also 50-state legal, making them a practical choice for riders seeking a compliant replacement or upgrade. Manufactured in the United States, S&S Cycle 550-1017 mufflers combine recognizable styling, durable construction, and carefully tuned sound in a direct performance-focused exhaust component.
