Bolt Size to Connect Header to Catback?

so, idk how this happened, but basically the bolts that connect the headers to the exhaust completely fell off after about 10 months of being on....:what:

so my simple question is, what size are the 2 bolts to connect the header and exhaust?
the headers are some generic Ebay crap and the exhaust is a OEM type R if that matters...

You mean the header to the cat?

If it's got the standard donut gasket and the larger holes in the cat, you need a spring bolt kit.

yeah header to cat.
so where could i get a spring bolt kit?
i'm guessing i could only buy it straight from Acura/Honda?

I think the bolt, spring and nut are dealer items dude. Probably looking at about 15 bucks. You can try a junk yard...

i got these from oreily. works great.

i ended up buying some from o'reillys and the one i bought actually did not have a bolt at the end, making the whole process a bitch!
in the end i got it on but it took forever..
screw spring bolts
