Exhaust header question

Hi, I am installing a full system Yoshimura exhaust on my brother’s bike. 2024 450RL

When I removed the stock header I was very slow as to catch any gasket that fell because that is what I was expecting. However, there was no gasket.

Is this how the 2024 450RL is supposed to be? I don’t see any exhaust gasket on the oem parts list. I am not sure if I should add one to the new pipe, or if it is not needed on this bike for some reason. Thank you.
