What is the tube sticking out of the top of the older sxr single pipes right before the muffler? Is it for some kind of equalization or silencing?

What I believe you are talking about is a resonator. It just helps tone the motor down a little bit.

It almost looks like a handle coming off the pipe. I kind of figured it was just for silencing purposes.
