This is what all modification is about... do it as you see fits. Many people do up their cars are nothing like what the manufacturer is done. The company made car for people. And people modified their car to suit them.
Welcome to the Options world (as the Japanese like to say

Racing beat does not have a dick like yours (which does not get up :p).
From the pictures of racing beat, it does have a bigger opening but it does not have an extension. And at least I have not seen a picture of one.
The similar design is RE Amemiya, and I am not prepare to pay 1000 bucks for one. It extension goes forward and have a large mouth. This may collect water in rainy days.

I won't collect water unless you drive through a river, Taka. Michael, the RB intake will have a CAI duct like this one available for it later in the year....according to Racing Beat.

So I am going to remove my VFAD this weekend and was going to gut my stock intake a throw a cone filter as recommended in this thread:https://www.rx8club.com/showthread.p...Ram+Air+Intake
If I do that, will adding this pipes help significantly? The pipes and cone filter cost me $66. If removing the VFAD alone will sound and perform the same with my stock filter I will return the cone and the pipes. But if they will sound better and offer more power I will keep them.
What should I do?

What kind of piping you are talking about?
I stand on my believe that the VFAD is for sound reduction only. There is no benefit of having it in terms of how the engine performs. I have recorded a lower intake temperature with a non VFAD direct tubing from the outside.
I never have problem with water to the filter.
Sounds are similar though but there is more but not significant noise from the front. You can prob can just hear it from the outside.
HKS has proven the use of cone filter benefit as long as you enclose it properly. In fact they recorded a higher power output with a system that have a box open ajar inside (if you know what I mean ... close but not air tight).

Basically my plan is to combine 3 different threads I have found on here.
First, remove the VFAD to increase the airflow
Second, gut my intake box and drop in a cone filter as shown in this thread...
https://www.rx8club.com/showthread.p...Ram+Air+Intake
Third, add intake piping to direct air straight into the filter. Basically a cheap air duct system as shown in this thread, the thread we are on right now...
https://www.rx8club.com/showthread.p...Ram+Air+Intake
My question is, if I remove the VFAD and drop in the cone filter is it really necessary to add in the duct piping? I would assume the answer is yes because otherwise, without the VFAD you aren't getting any direct airflow into the intake. Just wanted some other input.

Wow, some folks were doing some "interesting" mod's back in the dark ages.
I went another route; removed my VFAD and mated a Racing Beat Ram air duct (instead of blue poly clothes dryer pipes to my stock air box with a K&N drop in filter. Also removed the two plastic baffles from the box.
It's not absolutely necessary to add duct piping, as air will certainly find its way to your cone filter, but to make it closer to a true Cold Air Intake (CAI) the duct does serve to more directly channel outside air when moving.

Right on. Thanks for the input huey. I plan on replacing the pipes with the RB Duct when I can. But I figured since I am going to have the bumper off already I might as well try something!
I Considered the home made CAI option that puts the cone filter in the bumper... but I really don't see how the extra cost involved in that would provide much better results than just installing a cone filter in the stock box?
