Exhaust mainfold and downpipe connection

About the gaskets- I see on the website several inner diameter sizes. At Autozone, there's the 2 17/32" inner diameter and 2 1/32" inner diameter. According to the them, both should fit. But which one should I get? What effects does the inner diameter have?

Ones more or less 2" and the other is 2 1/2" . If it was me Id just get both since they're pretty cheap and see what comes out when you pull down the pipe , Its easier to take one back later on then have to clean up your mess and go back to the parts store in the middle of the project
