How can I tell which intake

How can you tell if it is the ls6 intake?
what size injectors are stock?
and im sure it has been asked before but how big of difference is there between the ls6 and the the FAST intake?

For your '01? Should already have one, the part number is stamped on the drivers side - mine came with 12561184.

you have it but just to be sure a LS6 intake does not have a EGR pipe going into the top of the mainifold just behind the TB. the LS1 intake does.

mine def does not have the egr, thanks for the info, would there be a big difference between this and the fast if so how much?

If you have not done a H/C yet than not that much. the FAST flows too much air for a bolt on car. once you H/C it though than you could net a gain of up to 35 RWHP.

thanks again, just looked at my intake #'s it is the ls6, would a fast 90 or 92 tb be a big increase or not.
