Exhaust Gasket Replacement

[dm36415]

I'm replacing my crossover pipe gaskets and muffler gaskets (or rather I'm having a local shop do it, but I'm supplying the parts).

I see there are different exhaust nuts available on the PP site, but from the description, it seems they are only for the heads.

Are there any special nuts and bolts I need to use for the crossover pipe and muffler gaskets, or can I just have the local shop supply some?

Thanks in advance.
