there can be clear net proxies iirc, which are essentially exit nodes, but they aren't recommended for fairly obvious reasons.
It's called an outproxy
The i2p outproxy is simply a user-specified proxy that i2p uses when you try to fetch someting outside the i2p network. I2p does not implement that proxy itself, therefore it is not part of i2p / it can't be called an i2p exit node.
There are no exit nodes on i2p.
