I should probably add, that this ticking noise only happens once the car has warmed up. So it's clearly related to heat. It's the same noise that the exhaust makes when you turn off the car and the exhaust makes a ticking noise when cooling down. But my car makes a lot of these ticking sounds when it's warmed up and idling. As I said, as soon as I give it a bit of gas or when driving the ticking is not there. Just when idling after the exhaust has warmed up.
I would imagine that a bad catalytic converter or resonator would cause issues all the time, especially when driving/revving the car and not just in idle once the car is warm?
