In short.. it's the bit of the exhaust that connects the head of the engine to the top of the catalytic convertor (in our cars). Otherwise known as an exhaust manifold in this country..

Correct me if I'm wrong, people  s:) :) s:)

Header is the thing between your engine and exhaust, where the precats and O2 sensors are. It's covered by a heat shield, so you won't see much though.

Looks kinda like this:

Its an American term. They say hood, we say bonnet. They say header, we say exhaust manifold...
