Welcome to the forums!
I don't think that a "no tune" CAI and cat-back exhaust will net you very much HP/TQ gain at all. The biggest issue with the exhaust systems on these cars is the restrictive cats. Everything back is just going to change the sound of the exhaust.
The 444HP/380TQ that the Boss makes is much different than the 412HP/390TQ that the GT makes. The Boss uses a different intake manifold, heads and cams to produce a torque curve that is almost entirely different than a GT. There are also some suspension mods that will enable it to to whoop you anyways, even if you are putting down the same power. Also, your stang only makes 412HP/390TQ on 91 octane or better. If you're running 87 you're actually putting down 402HP/377TQ.(1)
You said you aren't going with a tune "for the obvious reasons." What are those reasons? Many of us here (and on other forums) are running tunes and have no issues.
