So I just got off I95 at cruise set at 75 with air aid jr. I can not even hear my intake at all. Just some exhaust. Loaded down with a lot of weight!
6.0 Cold Air Is Way Too Loud At 75, How do you shut it up!

Do you find it loud with the CAI? It's really bad around 70/75. Which CAI are you using?

Sometimes when cats plug they sound loud through the induction.

It's not making any sense to me. The intake noise should be linear with throttle angle/load. Unless, somewhere around 80MPH, yours downshifts or the torque converter unlocks and allows the engine to spin a few hundred RPM faster, the engine should get louder at 80 than it is at 75. Or maybe right at 75 with TC locked in OD at that particular throttle angle, the engine produces a specific frequency that just so happens to be the resonant frequency of the cabin/your ears/etc. But then, there's always the chance that the muffler is contributing to this very specific resonant frequency. I'd put the stock filter box and filter back in and get an MIT.

I have an eBay kit. I have a real hard time hearing it at any speed. Even when I mash the gas I have a hard time. When it's idoling with the hood up the air noise is faint. I gave used a few k&n and air raid and never heard anything.
My 02 Denali does what you describe. It's like it has drone that exhaust gets, except in the intake. It happens at 60+ when I've been at the same throttle level for a while. I like the sound so it doesn't bother me. I'm stock with an Airaid jr. And a green filter.

Problem Explained! Ok, while talking with Volant and a few others, and looking at my driving, the correlation was always around RPM's, not MPH. So to use one the terms described here, it was a loud Drone sound. Essentially what is happening that when you have a CAI and Tuned exhaust, at some point you can, not will but can get to a point where the same harmonics are coming from both, and it is loud. Very loud. The Air Rad JR. gets rid of this easily as it uses the factory box, so you never hear the first harmonic. Sometimes you will actually have this so bad you will have to change both the CAI and the exhaust so they don't over lap. So at like 2100 RPM's, every time, the motor would be much louder, but when I accelerated, It would quiet down till it dropped down to the same RPM.s again. The reason why I went with the Volmant is that it is a sealed system, so your chances of having that front are deeply diminished because the box insulates it. It it is still bothersome, then back to the exhaust shop for them to change the tune. It's not common, but when you get it, it sucks.
So the reason why I am not doing the Jr is simply because I like the Vomant design with the forced air induction. Thanks for everyone on the input, it helped a lot.

Sounds more like exhaust drone than anything to me.

We will know soon enough, but the noise is not nearly as bad in the back seat as it is in the front seat.
