Once "search" is working, look around a bit before blowing your $$$. The fast intake works great, if you do heads and cam. Aftermarket MAFs do very little, and underdrive pulleys are fine if you're replacing a worn out balancer however very little gains for the money. Look into changing the rear end gears with the money saved from the above... a lot of bang for the buck.

You should have a plan before you start buying any mods. What is your end goal? For example if you plan to go with turbos down the road, don’t waste your money on headers and air filter now.
That said; depending on where you’re going with your mods, 1 7/8 headers are probably too big (unless you’re going big cubes down the road). The Fast 90/90 is pretty much useless on a stock motor. You’d need a pretty stout H/C package to see any significant gains from the 90/90. If your Vette is a 2001 you already have the LS6 intake. I’d hold off on the under drive pulley until you do the cam. It’s probably good for 6-7 rwhp but it’s a lot of labor to install and probably not cost effective on its own.
1 ¾ headers (Kooks, AR, LG), high flow cats or off road pipe, xpipe, a good air intake system, a ported stock tb, and a good tune should get you into the 340+ rwhp range, maybe 350 if you’re lucky. Corsa makes great cat back systems, but they (or any other cat back) really don’t add any power. Buy the cat back that sounds best to you.

Get the kooks if you plan on going big cubes or supercharger
If not I would go with LGs and a vararam for the intake

The 1 7/8 headers might be ok with a max effort 346 Procharged motor. Personally I’d go with 1 ¾ headers unless you plan to build a crazy forged 15 psi motor. Even at this level I have seen good numbers out of 1 ¾ headers. If I were buying new headers I would go with the American Racing 1 3/4’s.
