The injen intake is extremely loud. I was too loud for me. Another guy I talked to said the AEM is quieter. Between 2200 and 3800 rpms the Injen screams. Even trying not to be loud is hard to accomplish. I took mine off

Depends on what your idea of loud is...

I have the Injen and what is louder than stock is the turbo spool up and my TurboXS BOV. The intake sound is not like a normal normally aspirated intake sound, you know that deep growl sound. But rather a woosh and spool up whine of the turbo.

Not noticible from the outside from say 15' away, but noticible from the inside for sure.

I love the sound of my GFB BOV and AEM intake. Definitely louder than stock comparable to the INjen.

I have the AEM and find it a little abnoxious... it sounds like a loud sucking sound of air through a straw and when you let off .. chhhhhhhhh..

pretty cool if you don't drive mature friends and reletives around much (course if you did that you may have bought an Audi A4 or a Passat...)

I don't mind a loud growl like an exhaust but the AEM is pretty weird sounding and I'm either gonna have to get used to it or switch back to factory...

I found the Injen CAI to be very quiet on my car. The only sound that is obtrusive would be the BOV sound. I also have noticed it sounds like I have a cricket inside my car at times...weird....
