I feel like 'staying out of the water' is the best solution but not very good technical advice on an intake problem. Thats like me saying... "want to save money and have more productive time, stop wheeling and buying parts!" You can build a rig to handle water, they do it overseas as a religion. I believe its the US and Canada that are the only ones that actually tip-toe around water.
In-cab snorkles are fine, especially if you have a 4-6 cylinder, the higher volume of flow you can create by bumping up the tubing size, the quieter it will get. If you put it in the glove box, the box itself will deflect the direct noise. Not saying you wont hear anything, but it shouldn't be aggravating. And if your just putting around, I doubt you'll really hear anything at all. But, keep in mind backfires... i've seen a few and they suck.
But, there's a TON of other issues that come along with drowning your vehicles.... which is the main reason most people don't want to even bother dipping their feet in, in the first place.
If you plan on water crossing, you better plan on repacking bearings, greasing joints, checking/replacing fluids, EVERY F TIME. Also, waterproofing EVERYTHING, plugs, wirings, winches, distributes, breathers, computers, lights, yada yada.... anything electric or needs to mechanically function.
I have a v8 with a 4" in cab and the biggest filter I could find. Its exposed with no deflection of any kind. When driving around at 1000 - 1500 its minimally noticable... if I get on it, you know it, but again, not really all that bad considering. Ive ran a 6 cylinder with 3" exposed, just sounded like the fan on the blower was on medium...
Hope this helps.... good luck.
