Say no to the Flowjunk. Its good for 3 hp. The Magnaflow is good for 15 to 20 rwhp and tq. My car went from 13.3 at 109 to 13.0 at 111 with the addition of a Magnaflow catback. I was already running a lid at the time.

$1,500 max??
Longtube headers, off road Y-pipe, and a cat-back. Install them yourself it's not that bad. Or you could do headers and true duals dumped at axle (my choice
) If you have to pass emissions check how they do it because if they do OBDII plug ins you will be fine with O2 sims or a simple LS1 edit for the codes. Definately get that lid, best bang for the buck you can find. You should be able to do all of that for $1,500 or less and may (should) have some left over so you aren't maxing out your budget........or you could just spend the rest on something like cold air induction, tires, or subframe connectors. 
Edit: What transmission do you have??? If A4 you might be able to manage a converter/shift kit/cooler with installation and a lid. Would have to have drag radials to make it usefull though

If you have an a4 car, get yourself a converter, set of nittos, LM and an airlid, and have it tuned. If it's an M6, get an airlid and a set of longtubes and a catback, or go for the catback and a set of 4,10's. Either way, thing about doing some suspension/chassis mods soon too, tie up the frame ( my project over the winter )

Our numbers test very consistant ... in house or thrid party if testing is done correctly ... here's a test conducted for one of our Mustang systems: http://www.mach1review.com/ Its not an F-body but its representative of our products.
Just for Future information, I have revisted the current F-body system to create a new internal design muffler to further compliment flow and enhance the sound character. Power numbers are showing a minor gain but tone is much more refined.
