Cold Air Intake Question
I recently put a AFE CAI on my 07 4.6 F150 and when I get on the throttle now it sounds completely different. Its a deeper growling sound. Has anybody else noticed this on their trucks that are running an CAI?

I guess you could call it a drone. The truck just sounds completely different now under acceleration than it did befoer the CAI. I dont really mind it I just want to know what about getting more air causes this sound?

Yes, it's the normal "drone"
CAI's don't have the "ribbed elbow" that deadens sounds, just a flat curved tube. Excuse my lack of better terminology, my brain is on shut down today. Bill can get a lot of the drone out of most CAI's with his custom tunes.

The drone noise is cool at first. Really cool if your a kid impressing friends. But after a while it become kind of a bother. As dixie said earlier the drone noise can be tuned out. If you get the gryphon you can run level 2 canned tow tune until the custom tunes arrive.

 You could get subwoofers that drown out the exhaust! And, for some of you guys, not me! :angel: This would also drown out the annoying sounds you occasionally hear coming from the right front side of the cab. - Jack

if you look at any modern vehicle you will see all kinds of bends and boxes coming off the air intake. their whole function is to modify the resonance of the air flowing through the tube to reduce the sound transmitted to the engine compartment...
how does the saying go??? if its too loud you are too old...
