Unless you can modify the HEMI Hat to work with one of the CAI kits it won't be quiet. THAT is what makes the stock setup quiet. Unfortunately, to rig it so you have the HEMI Hat with the internal baffles to quiet it down you would in effect negate the benefit of the CAI.
You either have a CAI and live with the noise or you run the stock setup.
Now, with that said, there may be a compromise option for you. I have never heard one so I don't know if it would be any quieter than afull blown CAI or not? It might though.
360 Air Intakes makes a kit called the "Kool Shot Intake Kit" What it does is remove the HEMI Hat and stock air inlet tube and replace them with a piece of 4" tubing. It uses the stock air box.
Now, it is "possible" this setup may be a bit quieter than the full blown CAI kits that use the cone filter. I say that as I would assume you won't be sucking as much air through the air box as you would a cone filter mounted in the open. The HEMI Hat won't be there to muffle the noise but maybe this setup won't be as noisy as a full blown CAI? Might be in between stock and a CAI.
Kit costs $175 and you have a ton of color options for the tube. Here is the info on it
