「とおり」と「ように」の違いは何ですか
* 先生が言ったように、試験は難しかった

As the teacher had said, the exam was hard.

( In keeping with what the teacher had told us, ... )

  

  * ... とおり､ carries a stronger sense. "Just as he said" 

It sounds like a prediction : あなたの言ったとおりになる（マルコ 11:22 -24）。

The difference is small, but ～ように is more akin to "like ～", while ～とおり is "as
～". In your example sentences, the difference may be too subtle. But basically
using ～ように allows a small difference from the original, while ～とおり implies
something is done exactly in the same way.

For example, 彼が言ったように言う sounds like "to speak/talk like him", while
彼が言ったとおりに言う sounds like you reproduce what he said, word by word.

「先生が言ったように、試験は難しかった」 can be translated as “The exam was difficult as the
teacher had told me (predicted it),” and I don’t find any difference from
「先生が言ったとおり、試験は難しかった」.

Both 「通り/とおり」 and 「ように」 mean “as” and “like, and ”are saying the same thing to
me.

By the way, when I say this phrase to my English teacher, I would use polite
expression, and say 「先生がおっしゃった通り、試験は難しかった(です)」

To me they are interchangeable. However, if I’m forced to tell the difference
between “ように” and “とおり,” ”ようにsound a bit softer than ”“とおり、通り” as you see in
the following examples. But it could be just a ”気持ちの問題 – a matter of your
taste,” as we call.

ように：

好きなようにカットしてください- Cut it as you like.

彼女はまるで見てきたように話した – She told as she has seen it.

みんなで決めたように行動しよう – Let’s do as we’ve agreed on.

とおり：

法の定める通り – according to / abiding with the law.

約束（規則）通り – according to one’s promise.

予想（予定）通り – as planned, per schedule

定刻通り - in an exact time as decided.

計算通り – as calculated, as considered

みんなで決めた通りに行動しよう - Let’s act as per we’ve agreed on.

According to "A Dictionary of Intermediate Japanese Grammar", page 517:  
In some contexts, ように, the adverb form of ようだ, also expresses the idea "in
such a way"(just like とおり).  
However, Xように basically means that the way someone does something or something
takes place is like X, while Xとおり means that the way someone does something or
something takes place is the same as X.  
Thus, in contexts where the way is practically the same as X, ように and とおり are
almost interchangeable.

So:  
先生が言ったように: like the teacher said  
先生が言ったとおり: exactly as the teacher said
