Like it will be fine to get some?? I'm still stuck with my manifolds now. I commented this earlier I think, I know a lot of people run pacesetters on here, someone else mentioned I think some made by SLP, and what about doug thorleys?

There are a variety of manufacturers that make various flavors of headers for our trucks, shorties AND long tubes. The PaceSetter long tubes are popular as they are about half the price (or less...) than most of the others.
That said, headers of any description will be better than the stock manifolds, although, the worst piece in the stock system is the Y pipe..... You want as much flow as you can get on the upstream side from the turbo... more flow equals more power.

Is the y pipe a separate piece? Or, does it come with the cat?

Hammer, over in the 3rd gen FAQ has a chart on flows from various mufflers.. If you haven't purchased yet, you may want to give that a read.. In short though: FM's have NOT mastered flow- they flow only slightly better than OE.. They sound real good though as they use a chambered approach.. MagnaFlow and Borla use mostly baffled approaches, which 'whoosh' as opposed to 'rumble'.. they don't sound as good, but they breathe FAR better by NOT producing back pressure.
I have a magna true x dual in dual out muffler.. I swear, you can drop a golf ball THROUGH it w/o touching the sides it is so open.. Again, it whooshes more than rumbles, but it flat out breathes.. I have a pair of magna-flow high flow's no more than 18" in front of the muffler, so I get pretty decent scavenging I'm thinking..
If you are still planning, and haven't bought anything yet- it would do you a lot of justice to break out the calculator and measure/fit every aspect of that exhaust before-hand, and while taking into consideration future mod's. Just my thoughts on the matter.
good luck dude!
