Yes your right. I do love the look of the fast intakes 
. Actually though upgrading my headers and cai would cost more. I will be getting the fast 90 and tb for $900 and selling my ls6 $300 and my stock tb $50. So I'm really only spending $550 on it. Headers with y-pipe and a cai would cost me $650 easy.

Plus it would give you a chance to get rid of that horrible pacesetter y-pipe.
But it seems as though you've already made up your mind.
Looking forward to seeing your results!

Ha my y-pipe is welded to my headers. So they would probably be hard to sell and they are painted not stainless so they don't look so great... Plus the PTA of installing those again lol.

Your set on wasting the money, go ahead and do it, you might pick up a tenth, but do you really spend that much time at the track that it's worth it to you? 900 dollars seems like alot of money to spend on such a small gain. You could easily do a cam swap for less money and pick up 50 - 70 hp.

I wouldn't sell the ls6 intake, I don't normally sell parts, so I see it as 900. When I bought my z06 it had a fast 90 on it, I sold it for 850 and put a ls6 on it, took 300 of that and bought a nx mainline nitrous kit. Used 50 shot pills, only used it when I was starting to lose a race. Had it in the car for months and never used the whole bottle.
I went 12.4 at 118 mph in my trans am while spinning in first 3 gears, just had ls6 intake, exhaust with ms4 cam. You don't need that fast intake till your out of other mods and need that last bit to get in the low 11s n/a.

i gained 5rwhp/3rwtq with a non ported 92mm fast/stock ls2 TB over my stock ls6 intake/stock tb. this was on a 02 z06 with ARH 1 7/8" headers, 3" x-pipe, UD pulley, CAI and ECS big n/a cam. The gains were only above 5800 rpm also. Same dyno/tuner as before also. The dyno graphs are almost copies of each other until the very top end of the rpm range. 428/365 (sae) to 433/368 (sae) on a dynojet.

sorry i didnt realize you were thinking of doing this with the stock cam.If i was you i would do the cam first.Your going to feel slighted if you do the intake now,because you will notice zero gains,unless you dyno it and want to see the 6 hp you gained.It will really not help at all,your engine right now is not starving for air. slap a cam in it first

Just messing with ya.
I would not hesitate to sell a ls6 if I got a Fast (after it was on though to make sure everything worked out). Ls6 intakes have held steady at $300-350 since I joined this site. Even with all the used 90/92 from people going to 102s, the ls6 intake price remains constant.
So having it stuck on the shelf for a "just in case" doesn't do much good when he can get another one for the same price he would pocket by selling it.
But I do agree on his car there are much better ways to spend the money.

I would do another converter and MTs in that car-with traction 11s. Thats what did it for me.
Some other things:
Barely trip the lights when staging
Over inflate your front tires
Ice down your intake manifold
Yank your front sway bar if all else fails
When they come up used in classified.grab a bigger lid,bigger MAF and a Powerbond/SLP pulley. With a cam and Fast down the road that stuff will help.

You don't need it yet, you are literally wasting your money getting it with the stock cam in. The ls6 intake already outflows your ls1 heads if you haven't already upgraded to 243/799's and even then it still outflows it. Cam it, port your throttle body and buy some heads and still have money left over from buying a fast.
