John the PO of my H16 put a Cub muffler on mine & it is too short. I was thinking of maybe extending the tip with a piece of tubing to get me thru & past the bracket. In spite of the surface rust it appears to be a new muffler. He also put a Cub seat on it too
Sorry i missed your post i did test fit the cub muffler and while short it would work but i am going to keep the machine gun alive for now.
Out of my three tractors this one needs the least amount of work before use time to change to straight 30WT oil for summer and just fix my seat mount.
The mower deck is not so lucky needs bearings and blades ouch for me.
