i'm running Stage 2 as follows:
Cobb SF Intake + Box
Cobb Catted DP w/ OEM Cat-back
Cobb AP w/ Protune (i had issues with the OTS maps)
i ran the Q300 for almost 2 weeks and took it off. way too loud. i finally met up with someone last week who was running a Cobb DP w/ SPT cat-back and it was perfect. i plan on getting the SPT cat-back in the spring unless i hear the Greddy SP Elite...
youtube videos are useless in determining loudness IMO. some of the better quality video's will give you an idea, but you can't "feel" them by riding in the car for yourself.
hope it helps.
