At the crank or at the wheels?
In stock form, at the crank you're pushing 193hp. With your exhaust, CAI, and assuming your chip has advanced the timing for 93 octane, I'd say about 205hp.
The elusive and lone spacer dyno didn't show any real hp increase, but you most likely gained some more low end torque from it.
Headers won't give you any more hp unless you're heavily modded (300+hp). The stock 99-04 exhaust manifolds flow remarkably well, and the dyno will agree that there's a negligable difference with aftermarket headers on a near stock 3.8
