Trying to find the right intake
I purchased mine used on this site and someday, when I'm trying to squeeze out every bit of power, I'll eventually sell it on here and purchase a used FAST Setup that I find on here.
If you're looking to get away from the factory looking manifold, do as MYSTIC suggested. Have your LS6 painted.
The BBK has proven to have a slight bump in power over the LS6 intake. If coming from an LS1 intake, the BBK is a great choice because it's just slightly more expensive than a used LS6 intake manifold. But if you already have an LS6 intake manifold, save your money, you won't get much. PLUS the BBK can use a larger TB.
Some people complain about weight, but there's no way you're going to actually notice your car is heavier, especially when it's flowing more. It weighs about 15lbs more than stock.
Also, how would air that is being forced into the intake manifold suddenly become less dense inside the manifold? I don't think that oxygen inside is going to just disappear. The cold air outside the throttle body is what matters. Plus you still have a metal TB, heads, and block...
Bottom line: don't follow the lame metal heatsoak intake theory. It's shown gains over the LS6. But stands still compared to the FAST intakes.

The term "pissing away money" comes to mind. But if you really want to pay double for it that's your business.
This is why the entire heat soak arguement is bunk. The LS6 also suffers from heat soak, the BBK aluminum intake does have a little more. Almost every intake in drag racing is made out of aluminum includinig 6 second pro-mod PSCA cars, NHRA top fuel funny cars and rails, and every other fast class (8 seconds or faster in the 1/4). The incoming air passes thru the intake so fast the slight difference in temp is not going to matter. Especially on a boosted motor with intercooling and/or meth injection.
Bang for the buck the BBK SSI beats the LS6 hands down. The fast is good if your staying naturally aspirated and like to burn money for a small advantage in the upper RPM range.
Another thing the LS6 and fast will not stand up to harsh nitrous back fires. The BBK aluminum and other aluminmum manifolds will survive them. So that expensive fast or cheaper LS6 may end up a twisted piece of junk for you nitrous users.
