anyone tried to run a different intake tube w/ stock airbox ?

I did not care for the sound.  The pipes sound much better.

I love the sound with all the plumbing done and the VTA... Much more aggressive with the noise maker gone, like a larger engine almost, and the sound is more with me and beside me when I accelerate hard at any speed, but completely quiet cruising.

you say noise maker, but it's actually a baffle to quieten the intake noise right ?

DJE why did you remove yours ? "the pipes sound much better" ?? downpipes / exhaust sound ?

it's actually a resonator on the high pressure side branching off the tubing to make noise during acceleration... like those things you blow into at parties.......

yeah so it's not a "noisemaker" it quietens it and by removing it you get more sound. Right ? conflicting info threw me off.

things you blow into at parties ?! made me think of the kazoo my 3 year old had after a bday party over this past weekend. Maybe I'll go connect it to my BOV's

The "noise maker"  is actually a sound director.  It is meant to send sound towards the cockpit.  It is not a baffle or noise reducer.  The pipes I was referring to are the down pipes.  Mine are non catted and produce a very nice low tone a little louder than the stock catted pipes.  They make the engine sound pretty close to the way a V-8 sounds, under acceleration in the cockpit and at an idle out back.  I think they sound fantastic with the stock exhaust.  Not loud at all but, a nice deep tone.

First off dyno's numbers can be skewed a number of ways.  A lot of guy's run a lower octane fuel on stock map and then switch to premium fuel on the "tuned" version.  Be leary if the tuned and non tuned runs where not back to back.  Secondly, most dyno's make the runs with the hood open.  This is not how cars run on the street.  Only way to really test heat soak is in a live "on road" environment.  JMO.

VERY GOOD point about dynos with hood open  ... its easy to  direct cool air to  the intake and reduce engine bay heat .

All true… dyno results can be changed if conditions are changed…
but back to back dynos in the same conditions still do a pretty good job of demonstrating whether their are any performance differences in different configurations or no gain… True this is shown in the difference between the two configurations performances although not necessarily the absolute numbers.  (heck it's why we race!). Check out this thread as well as just this post… food for thought about practical application and testing of dyno and street conditions adjusting the same variable in each one.

The test of the Box vs Wide Open Intake.  If anything, having the hood open with a fan on should have given an advantage to the Wide Open Intake.  Yet, it was still < 3HP higher.  That puts them just about even in my book.  I have to say that Ford did a great job on this one.  The only thing to improve would be to trim the outer hood molding ala BPD.
