Default TBSS intake or LS1 on 5.3???

I keep reading that the LS1 intake kinda sucks as far as factory intakes go, I have a TBSS intake off a 2006, it's not to ugly if you smooth down the ribs. But who cares anyways it's in a mustang anyways, is there a performance gain over the LS1 intake? Obviously there will be a low end torque increase but I may go FI later but either way which is better overall? Engine has the heads and cam from the TBSS installed as well what you guys think?

I hear truck intakes outperform LS1 intakes all the way through the rev range but LS6 intakes beat a truck intake in the upper rpms.

Going in a DD street car, convertible at that, so super high revs are few and far between.

While it is true that the LS6 just barely outperforms the truck intake that is the old Gen III style. The nnbs or tbss intake clearly outperforms both.

now thats the first time someone has said that it outperforms both to my kmowledge! with all the bracing and addition of the IRS in the rear I certainly could use the dded torque with a truck intake, as to appearances like I said its in my mustang so opening the hood either way I'm getting looked at sideways lol,

Keep in mind the comparisons between intakes is on a larger 5.7. On the smaller 5.3 with stock cam, you wont notice any difference.
I went with the LS1 for hood clearance, and because they only cost $35.
