Man... how much power do those polished valve springs give you 
So you have a cam w/ stock manifolds... dude get headers first, then a re-tune.
The FAST will only give you more power w/ a large cam or larger motor, otherwise stick w/ an LS6 manifold.
My car might get 10 rwhp w/ a FAST 90/90... not worth the $1200.

Ya, probably headers. Maybe look at getting CNC'ed heads at some point as well, after I bought mine I found a local shop that could have CNC'ed my old ones. Anyway, the bump in power for **Me** (could be different for others) with the CNC'ed heads was more than the bump from headers, but was done after the headers.
Also, high flow cats are pretty good. I don't think I'll buy much with putting in the off-road pipes, so I just leave in the cats. We have smog test where I live, visual inspection included. So got to have them.

And the valve springs net me about 100 RWHP i'd say
Oh and I do plan on a much bigger Cam latter after the headers intake, I will do the cam then get a tune. My goal is about 420 to the rear wheels.

I am very strongly considering just putting in a crate LS2 or LS6 and an RPM tranny I just need the ten K which I can get out of my stratus when I sale it. While I'm at it I think I will replace all the radiator mounts, re mount my horn and replace the brake cooling duct and the rest of those crap a$$ rubber/plastic pieces under there.
