Yamaha Motor Co., Ltd. 4YE-21446-00-00 Muffler Stay

The Yamaha 4YE-21446-00-00 Muffler Stay is a bolt-on mounting bracket that secures the muffler to the motorcycle frame, maintaining correct exhaust positioning and reducing vibration for better durability and noise control. Constructed from OEM-grade steel or alloy with a coated surface, this formed bracket provides mounting holes at the muffler/frame connection point and is designed for exhaust mounting systems on Yamaha motorcycles (model-specific fitment). Designed for replacement, repair, or retrofit, it helps restore mounting integrity and reliable operation, with common OEM-compatible replacements including Yamaha 3Y1-21446-00-00, 2A6-21446-00-00, and 1T3-21446-00-00.
