I put mine in Fri as well. I think it's perfect as far as sound goes. It's not obnoxious at all. You hear a nice growl at WOT, and you don't notice it at all during normal driving. Install was a piece of cake. I put the whole Airaid assembly together the night before (while watching TV). It took some wiggling to get the lower OE box out, but not too bad. I forgot to attach the CAI snorkel when I initially put the airaid box in
. I didn't remove the neg batery cable either. I removed the relay for the PCM instead. I didn't know if I'd lose all radio settings, so I didn't want to remove battery cable.
