AIS Filter System

Thinking of ordering a AIS system , do they add any more motor noise then the stock ones. If so how much?

The AIS by itself does not add any noise. Once I did the fender sleeve mod I picked up a small amount of whistle from the turbo but none of the intake drone people mention with the 6637.

That is correct. It will be nice and quiet too.
The exhaust won't be.

I really like my sound. Kwik's is an inch bigger (EXHAUST). I'd like to hear the difference.

I don't get the "drone". And the in-cab noise is gone.

Last summer I talked my dad into the 6637. He pulls a lot of loads in the mountains of NM. He is VERY VERY VERY hard of hearing. Well, one day on the phone he said "Dam that filter is loud when pulling grades". "Even on the steep one lane Forest Service roads with the horse trailer". Now that's saying something. If he can hear it, it's loud.
Oop, there's another tangent.

Was told by the exhaust place thats putting it on that there wouldn't be to much difference, Its a Magnaflow exhaust system, so I'm hoping not to get to loud.
