Stock catback HP limit with boost?

I have a fully built block, with GT3076R pumping 18psi boost.
We did a back to back gains are definitely possible without getting much noise extra.
The biggest restriction is the factory Y split.
I have a custom made 3inch turbo back, mated to to stock exhaust cans. Nice and quiet!
