Is to hang the exhaust from the insulator on the subframe. Standard mounting point

jeeze none of this stuf came with nuts. it came with the necassary gaskets and bolts but no nuts!!!!!and their metric 10.9. so far all i found was metric 12 and 10 nuts. why would it hang from insulator?

I dunno... My CS cat-back doesn't have that, I don't think. Maybe it's only on the N/A version.
