Header mod or no?

You could go with the following:
1. Dewala air intake guide
2. Three inch intakes, but you'll need a retune
3. Port and polish your throttle bodies
4. Upgrade your throttle bodies with the Daytona throttle bodies, but you'll need a retune
5. Swap out your upper intake manifold to a Motordyne or Z1 model, or have yours ported and polished
6. Port and polish your lower intake manifold or upgrade to a Z1 model
7. Light weight / under drive pulley (I know there are mixed opinions on this, but it is an option)
8. Consider a better cat-back set up
9. Delete the HFCs and get test pipes (you'll increase rasp)
10. Upgrade the cams, but that's expensive and labor intensive.
11. Like you said, you can upgrade the headers, but your drone and rasp may increase. I can't speak to this because I haven't upgraded them........... yet.

I can't think of anything else right now, but if I come up with anything, I'll respond with it.

Tractionless

Wish I would have seen this a couple of months ago when going CAI. The intake temps. are exactly the same as my well insulated under hood open filter elements and don't cool off any faster when in motion.

Wonder if it can be done without removing the bumper cover.............again. Considering my '10 Base bumper cover radiator inlet slats are deleted, it seems it may fit through the opening.

Just curious, you have long tube or short ram intakes? I can't see how the air guide could be installed without taking off the front bumper.
