APS will not sale you the inlets.i already tried,Peter said "they only build the inlets when they have a order for a whole c6z06 kit".then of course after he says no he gives you one of these stupid "
",like he helped you out.
as far as any major gains ,i was not able to get 12 psi and with my homemade inlets i can get 14.2 psi all day long,with the controller turned down.more im sure if i had a built motor.
befor the 3'' inlets i ran around with just screens for a few days(making sure not to go in water or dirt).
APS made like around 900 rwhp with 2.75 inch hose so i would say the 3'' i have would be enough flow for your build.

Here is what I did.
I also went with a larger filter to allow more cfm.
The filters supplied with the APS kit flow just enough cfm to support about 650fwhp, so installing a larger filter can allow more inlet airflow, and help to reduce the choking effect that is happening.
I know this setup is not optimal, but I think it is better than the crush pipes, and the new hose to the turbos is 2.75", with a straighter path, so it should flow quite a bit better.
Unfortunately, I won't be able to test it until spring, so I won't find any problem areas until then.
Hopefully, there is not too much interference between the lower a-arms and the hose.
I do think as everything moves around, it should be OK, but I won't know for sure until I road test it.
I did cycle the suspension up and down a bit, which did look like it might work OK.

So will I! 
If the roads clear up over the next week or so, I'll take it out and put about 20 miles or so on it on the back roads around here, then back on the lift to check for any distinct signs of abrasion, or any other problems.
The new hose is pretty tough, so hopefully it should work out OK.
I'll let you know how it turns out, if I can get it out there.

Quick update.
Got the car back together with new hose routing as shown above.
Put about 15miles of back road driving on it, hitting alot of bumps to create any potential fit issues to be prevalent.
Put the car back on the lift, and there were no major signs of problem areas.
Actually, it looks like it might work out very well.
Of course, only more miles will tell, but initial results were positive.
I turned the boost controller to it's lowest setting, and layed into it a bit (not WOT), and from visual testing(I was not logging) it seemed to hold boost better as rpms increased.
However, i won't know for sure until I can make a full log at WOT.
So far, so good.
Maybe if we get a stretch of decent weather, I can perform a more thorough test, with logging.
Overall, I think it is a success.

I am looking into manufacturing some much better, Z style inlet tubes 
We made over 1000 thru the filter and tubes on the Z style, like Ed Traylor 
IPS has posted some 15-20% gains with removing the inlets and running screens, which I will test at a later date

We just got our new mandrel bender so we are trying to replicate a prototype that we found to work much better, with some cost effectiveness, because the prototypes where way to pricey for most consumers.
As Lou stated we have seen confirm 15-20% increases in metered air flow from removing the intake pipes and filters, the filter alone were the almost half, but you have to have them!
Since we are currently doing some updates to one of those cars, he is defiantly needing the additionally air!
If your close to Lou or myself, im certain either would equally be able to create a nice turbo inlet pipe with our testing an knowledge!
Good luck

Sounds good.
I am looking into several options right now, and don't know if I will be staying with the APS system or not.
It's possible a supercharger might find its way onto my car before it's all said and done.

You can order straight from these guys.
I went with the 70mm, since it is 2.75", about .25" larger than the APS hose on the turbo side.(same 2.75" size as filter side hose)
They also carry regular 3", but there isn't much room, so I went a bit smaller.
I believe they do have a 12.5' minimum purchase, but if you run it to the filter area, you'll probably need most of that 12ft.
I have to give credit to AtomicC6 for the rfh hose suggestion.
I did pretty much what he did to his car, so I have to give credit where it is due.
I just had to search for someone that had it nearby.
I plan to run this as long as it lasts, which I won't know until spring and I put some real miles on it, but I think it will be fine.

When I removed the old APS filters, the center cone section was fairly full of sand and small stones/road debris!

Did anybody ever make new inlets for these kits?
