Here is a nice reproduction Fairbanks Morse pot muffler. This muffler would also work and look great for any engine with 1 1/2 NPT. Please check out the pictures and see if you need it. Approximately 10 1/2 tall. Approximately 7 1/2″ diameter on the ends and 11″ at the widest point. If I make a mistake on measurements or you feel something is not as described please let me know and I will try to make it right.
