New Aftermarket dual port muffler. I have installed the dual port kit. You will receive the muffler as shown in the pictures.
My stihl ms311 is not included. This is for a dual port muffler only.
Pictures of my ms311 are only to show you how the muffler looks installed. Powerhead is NOT included.
Again this is for a dual port muffler / exhaust system ONLY as shown in the pictures.
Feel free to ask questions. Fit’s ms391 and ms311.
