What system replaced secondary air pump on T7 cars?

I'm working on a new theory on my noise.
It's my understanding that 99 and earlier cars had a secondary air pump that forced in additional air for the first few minutes of a cold start in order to help heat the cat.
I also understand that some change was made after that.
I assume that there is still some system that injects additional air during a cold start on T7 cars. Does anyone know what the components of that system are?
The timing of my noise indicates to me that it may be related to that.
I'm curious.
THanks!!
