You hear a refined 'roar' under moderate to full throttle. Under normal throttle it's fairly quite. Not as quite as the stock intake but not that noticeable.
Mind you it's not CARB (California Air Resource Board) approved so keep that in mind when your smog inspection is required. There are few ways to deal with this issue. PM me if you need details.
Although I've never had my car dyno'd ( with or without the intake) I can't positively validate the HP or torque gains claimed on the SRT web site or by independent CL testers.
I personally 'feel' a little more power but it just might be the wonderful roar you get from massive amounts of unbaffled air giving you that surge.
Good luck!

I like mine SRT Intake, sound wise
Power? some gains at top end. I noticed much more power during winter time with temps 30 degrees and less. I think that heat shield its joke. Metal Piping is another issue i have, can you imagine 90 degrees outside with air trapped in the engine bay after 20 min. ride. SRT piping will be hot as hell also air going thru intake will be much warmer, that means no power gain, i'd rather say power loss.
I'm currently working on piping insulation, and than custom air box
So if you're concern about SRT sound, don't - why? coz you don't drive in 4K-6K RPM range every time you're behind steering wheel
Oh, and my gas milage got better, when i drive resonable

i solved that problem with a $5 dryer hose from home depot - the flexible kind...i had it running from the bottom front next to the fog all the way up right to the filter so that it was receiving the air from outside... it cooled the that area significantly.. big difference....

I installed my SRT first (nice sound, not incredibly louder until you really mash the pedal). Then I added the borla exhaust...it sounds 100% different with the combo...louder, grumblier, meatier. The SRT whistles right before the car shifts, I've had several people ask me about the supercharger...haha it's just an intake I tell them.

The best thing to do with cold air intakes is to make a custom box for it. Some guys use plexiglass, sheet metal, anything to seal out the hot air from the engine. The colder the air, the better performance you get out of the intake. Using a gutter extender will serve no purpose unless it leads to a sealed enclosure. Here is a pic of a custom job for a GS4 with an SRT intake.

as far as my gutter extension.... not working...what do you think a CAI..does....it goes outside of the engine bay so it can receive colder air...
i owned the SRT and did the mod...i have proven experience that it did supply colder air to the area..was it optimal ..,.. NO, but it was better having air rushed from in front of the vehicle and from the outside of the vehicle and then have it go directly to in front of the filter than having the filter sit there and just suck up the hot air around it.

sean..the point is to get fresh air to the area of the filter which it did..oppose to it sucking the hot air that was in the engine bay.. and that isn't always the case that its one continous long tube... if you are familiar with it then you would know if you put a bypass valve on it (ie.AEM) it isn't continous anymore yet it still does the job....
As far as the discussing this with you i'm not... like i said i ACTUALLY OWNED the srt intake and had it on my car and i know the difference it did on my car. you should remember...you saw my taillights on several occasions...
