From a fellow newby who just bought an '04, you may want to search old threads first, then ask a more specific question if you have one. That way people here will be less likely to tear you a new asshole for shits and grins.
But since I am doing the same research, I will tell you that the first thing you need to decide is cats or no cats. No cats option is less heat, but you can't make emissions. Also if you want cats, unless you go with 3" hi-flows, you get stuck with a 2.5" system. Then you need to decide crossover or no crossover. No crossover is less heat and weight, but some people say the car sounds better with it.
I'm going the no cat, no crossover route. The corsa track is popular, but expensive. Some reported fit issues on the morg, supposedly no drone. The Mopar race is much less expensive, but some people don't like the sound of the Borla muffler it uses. I'm probably going to end up with the Mopar Race, but am also looking into the Roe Racing exhaust, which uses shorter Borla mufflers and is supposedly lighter. I'm waiting for a return call and will order something tomorrow. PM me if you want further details.

We have had great results with the Belanger setup. There are several advantages of this particular product:
1. Stock cats (all 4) are removed and replaced with the integrated high flow cat
2. Crossover eliminated, lower heat
3. Aluminized material for lower temps.
4. Relocation of O2 sensor, no check engine light issues!
5. Sounds great!
The setup is made for mating to Belanger headers, not stock. Mating them to stock is quite easy for my fabrication team and the install is nice and clean. Call me with questions 972-679-7900
