Gary, Question for you, on these backwards pipes. Mine are just like this as well, So last summenr I thought I would fix this little concern from reading the forums. I purchased 2 new pipes,, good thing I did because 1 had a bit of "rust" and looking close at it,, had pin holes in one pipe. Both replacement pipes were identical to the 2 I took off,, But comparing the indivudual sets,, the pipes are diffrent in the bends. So tried as hard and as long as I like,, "disregarding the pins that the claps fit through" Mine on the 74 model would only go on the 1 way,, This was because of the unique bends each pipe has,, Ya, I could put them on, bot they wouldn't fit in the cowling hole. Are we sure that they aren't suppose to be "backwards" as per say?
