Nova SRi exhaust manifold and down pipe (or something that fits 1.2 spi)

[corsa_nova_boy]

Hi all, I'm looking for a SRi manifold and Down pipe or something that will bolt to a 1.2 spi head as I recently bought a decat for my 4-1 manifold and i was told the 4-1 manifold was for the sri but turns out its the SR manifold meaning the ports don't line up. Any help would be appreciated.

Thanks :)
