The FMF Q4 Slip-On Exhaust, Part Number 043377, is designed for Suzuki DR-Z400S motorcycles from 2000 through 2009. This performance replacement muffler uses internal baffles, chambers, and advanced sound-absorbing materials to help accelerate exhaust flow while maintaining controlled sound output and minimizing power loss. Its slip-on design provides a practical upgrade for riders seeking improved exhaust performance without replacing the complete exhaust system.
The FMF Q4 is engineered to produce sound levels well below 96 decibels on most motorcycles, helping it meet strict trail and riding-area sound requirements. It also includes a U.S. Forestry-approved spark arrestor with a maintenance-free stainless steel screen, making it suitable for responsible off-road and recreational riding where spark-arrestor compliance is required. Durable construction and FMF engineering provide dependable performance for regular use.
