what bolts/nuts replace the factory exhaust downpipe studs

[seanramey]

Hey all, I bought an IE shorty header, it supposedly bolts right to the factory downpipe, but I will need a bolt and nut setup to replace the factory connection from the exhaust manifold to the downpipe, and is it easier to remove the nuts connecting the two off the car?

Thanks for the help.

I got some metric locking exhaust nuts from Napa and some fully threaded metric bolts from our local hardware store for a similar project.
