I love the "drone" as you say. but under 2200rpm its just like stock. over that it has a deep humm, then over ~3500 it is loud but deep. then over 4500 through to like 5500 its really loud and deep, then at 5500 through to 7500 its f&%king awesome, friends say its like being passed by a GT spec race car.

 

^ Lol you like droning??

 

Well what is it? lol... I just kinda assumed it was that humming sound?

 

if you do not know what it is, you will in about two weeks and hate it

 

^ Lol so true.

It's that really really deep sound that only occurs between 2k-3k rpms. Eventually, you'll notice you get headaches more often.

 

something too look forward too, but soo worth it

 

Ohh I already have that(did the system like 3 weeks ago). I love that sound lol. I'm a super rev head so the sound of engine is a great sound to me. So added the AEM CAI tonight and its changed in tone again. Not as much drone, but a nice shrill(not tinny, like a V12) at high rev shifts.

 

Sick sound............
