Muff-L-Aire II

Quiet down engine noise while maintaining peak operating performance with the DU-BRO Mini Muff-L-Aire II. Designed as a universal expansion-chamber style exhaust solution for small-displacement glow/nitro aircraft and model engines, this classic muffler features an adjustable strap-on mounting system that fits a wide range of engine configurations without requiring customized exhaust headers.

Key Features

• Universal Fitment: Engineered to adapt easily to small two-stroke glow engines ranging from .09-.35 cu in displacement.

• Effective Decibel Reduction: Provides optimal exhaust dampening and a lower-frequency engine acoustic output while keeping backpressure balanced for smooth idle and throttle transitions.

• Strap-On Mounting Design: Attaches firmly around the cylinder/exhaust port area with high-strength straps/clamps, eliminating the need to search for hard-to-find bolt-pattern exhaust adapters.

• Compact & Lightweight: Minimizes front-end weight additions to preserve center-of-gravity balance on smaller airframes.

• Corrosion-Resistant Finish: Durable metal construction engineered to withstand the heat, high vibration, and corrosive oil spray typical of nitro and glow fuels.
