Im looking into letting my LO3 Pro/Am to breathe

. I was never really into the Magnaflows or the Flowmasters, so I'd figure I'd go with something different. Opinions are welcome. Since I'm getting to the basics of Headers and don't know what the fugg I'm doing (

), I need opinions also as to what headers and etc would be a good combo with this nice system.
This Is The Cat-back I'm Looking At
Pros:
Stainless Steel
1,000,000 Mile Warranty
Sounds Nice (from what I hear)
3 in.
Cons:
Might need to recut rear bumper to fit
Expensive ($900)
<<<<Hasn't read up on his exhausts lately
Yea, and you are free to give me

<<<these looks, cuz I don't know what the heck I'm talkin' about. I NEED OPINIONS.
And by then, I hope to sell my 86' to help pay for the upcoming suspension kit / labor.
Thanks for reading my stupidity! I'm kinda tired too so...
