Air injected reaction supply tube. It puts air in the exhaust to help the cat burn fuel that passes through the engine unburned.

Re: What is this?

do you have to pass emissions? if not block it and retune your carb. delete that smog pump too and block the lines that run into it. truck will make a little more power run a little smoother.

What year model is the truck? Emission testing is only required up to 24 years. Buddy
