Go with Headers, no cats and stock Ti muffler, you will love the sound and keep 500.00 plus in your pocket. You can always buy a cat-back system later.

To each his/her own. But IF (big IF) you get caught without cats, you are subjecting yourself to a possible $10,000 fine and imprisonment. Plus, some have said on this site that the exhaust gasses smell "funny" without cats. As much as I'd love to run straight pipes instead of cats, just not worth the risk, IMHO.
You can see from my sig what my preference is. BTW, I chose GHL's because they were reported to have no resonance, whereas the Stingers did noticeably increase resonance, from what has been posted on this site. I can tell you that before my headers and high flow cats, there was no additional resonance in the car after installing the GHL's. I did have a partition by then also. That helped.
From my perspective, unless there is a substantial cost savings with the Stingers, go with the GHL. They are both very good systems, but the drone can get to you pretty quickly.
Good luck.
