ARK grip gasket size

[ASemper]

Upon inspection of the system I noticed 4 gaskets are provided with 6 joints in total. I am assuming the gaskets between the cats and Y-pipe are the ones not provided as the other 4 look the right size for the joints further down the system.

 

If I was trying to get the 2 I need tomorrow, what is the correct size?

 

Thanks
