You need a piggyback for the system. Passnu2 was onto something long ago, but he didn't venture too far into it. The old 3uz-fe from the 05's and under have the same engine, so their intakes lined up with the 06+ okay.
I believe it was Swift racing or something, I forgot..... You can always do a search.

The best you can do is add a performance panel filter like K&N or Tom's.
And replace your catted mid pipes with an Invidia resonated mid pipes.
Your axle back exhaust can be replaced with something lighter perhaps.
And if you're lucky you can de-cat your primary exhaust manifolds and have O2 simulators installed to cancel out any potential CEL.
Anything else and you're asking for trouble. Unless you can find a way to crack that ECU and keep your parameters stable, you will not be able to play around with timing, and boost should you decide to force induce your engine!
Here's what an invidia mid pipe looks like on a V8. The flanges that connect to the headers need to cut off and rotated to fit the angle of the stock flanges. Also, the O2 sensor bungs need to be relocated. Nothing a good exhaust shop can't handle in a couple of hours!
Stock Midpips
I used an Apexi Neo A/F controller with a custome made harness I purchased from Passnu.. it didn't work. I was able to run a TRD supercharger on my GS460 but things didn't work out too well as I was not able to control A/F and that almost blew my motor!
Here's a video of what potential a GS460 could have if it was possible to keep it reliably stable!

You will not get any relevant performance gain unless you can crack the V8 GS ECU. Which cannot be manipulated.
