There is that pesky factor associated with injecting fuel into the exhaust gas stream and having it burn. This adds a lotof energy to the exhaust gas stream. (That's why we do it.) The result is an observed increase in both the pressure and the velocity of that exhaust gas. Bernoulli was aware of this variable, and he said so. But he didn't write his law based on making a major chemical and physical alteration to the fluid stream.

Exhaust gas pipes are silver and are made of metal.
Could be a blown head gasket or one of your mates is playing tricks on you. Is there any water in the engine oil, it will be a creamy white sort of colour.
