Centre pipe gasket and backbox bolts

[skymera]

I'd like to double check this gasket fits before I buy:

And I need to attach a standard back box to the centre pipe, what size bolts do I need?

Will these do? Or do I need bigger size?

gasket looks fine to me skymera, and the oem captive nuts are metric fine, but the last copy backbox i fitted had normal m10 nuts welded on

Thanks, ordered the gasket

was looking at a box like this

Not sure if it has any bolts/studs already and just needs a nut

ahh yes, they,re welded studs/bolts not nuts i believe eh, i think you,ll find any copy one like that will have normal m10 threads

oh ok, saved me a few pennies.

Just need some exhaust rubber mounts if anyone has any? wink wink
