Re: Exhaust manifold threads
Here's a die for $42.00. I bought one a while back. Pretty nice quality but took a while to arrive from China. I had to break my rule of not buying from Chinese sellers, which was hard pill for me to swallow.

Re: Exhaust manifold threads
The last time I saw one of the new exhaust manifolds it was the 25-27 style. If you want the earlier type it may have to be an original.
The inevitable often happens.

Re: Exhaust manifold threads
A friend of mine, who also participates in this thread, had a manifold with unsalvageable threads that he was desperate to save. He took it to a machinist who cut off the damaged threaded end and then made a new end with more common coarse threads and welded the end to the manifold. Then the machinist made a new nut (from steel) with threads to match the new threads on the manifold. I'm sure he had a manifold worth its weight in gold by the time all was said and done, but with the nut screwed on, you can't tell its not original.

Re: Exhaust manifold threads
If you can deal with the welding aspect, a common pipe union could be adapted for connecting header pipe and manifold. Welding might be avoided by inserting a pipe nipple or short length of exhaust pipe in the manifold outlet and securing it with a bolt.

Re: Exhaust manifold threads
I bought a new one for my 21 Touring. Worked fine for me.
