If your muffler was plugged you would not be able to go 70, well maybe with some resistance if it was only partly plugged. But it would run OK at low speeds and your overheating would be at hiway speeds not at idle.

In other words your symptoms do not point to a clogged muffler.

The water distribution tube is a metal pipe slightly flattened into an oval shape. It slides into the engine block behind the water pump. There are holes strategically located to allow water to flow out of it to each cylinder.

This tube extends the length of the engine. To get it out you have to take off the water pump and fish it out with a bent metal rod or special tool.

But check the engine temps first. As long as the front of the engine is more or less the same temp as the back the water tube must be OK.
