BBK H-pipe

What is the small 90 degree pipe fitting that right behind the hangars? I blocked off the O2 sensor ports but I'm not sure what the other is for.

Your help is greatly appreciated.

Yep, for the smog pump. I have the same pipe on my car. Helped a good deal I might add. If you aren't running the smog pump on your setup, simply cap off the tube and you will be good to go.
