Yea for my wallet I think I'm going the regular old Unequal Length header route
Even though they are considered shorties, I've seen some Unequal Length headers out there when I've been researching (Unequal Length)/ Equal Length/ Long Tube headers) and the UL for the ISF don't exactly seem too short compared to some shorties out there, they look like an in between shorties and equal length?

^^^^I've had both and I do! However, if your interested in sound, the EL headers greatly reduce the in cabin drone. Also the exterior sound at idle is changed. The UL header has a more rumblier rough idling sound. Almost like an old V8 with a cam. It's hard to describe and that sound comes through to the cabin when idling.
The EL header has a much smoother even sound and as I said with much less drone. I have PPEs dual mode exhaust, and with the UL header, when driving on the FW at the resonance RPM (1900 to 2100 RPM) I needed to close the exhaust when speaking on my cell phone (Using bluetooth). With the EL headers I can speak on the phone and not close the exhaust.
Edit - I guess you can call it a more refined sound

So your saying again that you've had both the Unequal length shorties & the Equal length shorty headers that were originally designed for the RCF, but PPE found out that they do indeed fit the ISF just with a simple modification for a smaller flange 60mm? Or have you had all three UEL/EL & Long Tube headers from PPE?
^^^^I wouldn't call it a choke point, it's just that the outlet flange size from the exhaust manifold/header is different on the ISF vs the RCF. An RCF header won't mate up to a non modified exhaust, either stock or third party, unless that exhaust is made by PPE.
I will obtain the difference in size an post here.
EDIT:
Flange Exit size Information:
ISF - 60mm (2.4")
RCF - 65mm (2.6")

We just sold a few of these sets that were just delivered last week. I will reach out to those customers to get videos and sound clips. I know the one guy has it paired with the Apexi exhaust and the other with the Meistershaft GTC.
Pretty quick turn around time as well on these headers.

I'm getting close to purchasing headers and now I'm thinking of waiting for the dyno results for the EL RCF headers on an ISF before I make my purchase
I'm wondering if they are going to put down better numbers than the UEL headers and weigh that against the cost increase of $1200...........

To be succinct: the primaries are elongated 12" before the merge collector.

I see what your talking about Lou, how are they treating you? You going back to the dyno to run more numbers with them? Also are you planning on getting one of the tunes available to compliment the headers?

^^^^I'm happy with 'em The atmosphere in the cabin with my exhaust open is more hospitable than with the UL headers. And I feel (I think) a bit more spunk in the lower end and the top feels strong also.
As far as a tune, right now I'm on the fence, leaning toward no.

Can we please get an update on these El headers from those who purchased these or from those who went from UL to El. I'm in the process of purchasing headers and was wondering if the 1200 premium is worth it since I only plan to do the header install once.
Sound clips?
Dyno graph?
What type of modifications was made to fit the headers to OEM or aftermarket exhaust?
Thanks

does the Equal Length shorties sound similar to the Equal Length Long Tube?? just wondering if anyone has a video of them.
been eyeing the headers for months on end on the figs page, but my innerself tells me dont do it huuuuuh.

it does not get much rawer than this, but working on the completed Ti cat back and hopefully can share that soon. Just been too wrapped up to complete the fab on it. This is single muffler, single cat, it's quite loud.

Don't push your luck its hard enough getting the original ppe extractors over here 
and make sure your stitting down for the price.
