This may be controversial, but please hear me out. Unless the emissions test is a simple OBD-II check and no underhood visual, you won't pass with a supercharger.
The Maggie 2650 and the new Whipple 3.0 are both made for high horsepower levels that are unattainable safely without serious fuel system investment and modifying internals. If you just want to slap it on, you'll be limited to 550-560 rwhp, the S/C will run well below its peak efficiency range, and you'll still need at least a minimal fuel system enhancement, say, a voltage booster... and then you'll still be running on the ragged edge of failure.
Also, if you want to save money and look into the non-forced induction path, the problem is you're even less likely to pass emissions with long tube headers and removed cats... E85 could be a solution, but you said you could only use 91 octane, which is dingo piss, even 93 is slightly too low for hot temperatures. Increasing power output through NA or FI upgrades will make things much worse (again, E85 would be your friend).
As my high school mates would say, you can't remain a virgin and also have kids
. Don't straddle the fence, your car is a special edition already very good even in stock form and worth keeping intact, but if you really want serious power, you need to let go of these self-imposed baby step limitations.
