ATP makes something similar to this as well, looks better imo, no color option though http://www.jscspeed.com/mazdaspeed3/intake/atpturboinlet.htm
Finally got my RPMC Turbo Inlet!!!!

The ATP pipe is a notoriously bad fit, and it doesnt work with alot of the aftermarket intakes available. There have been a number of people who've tried it and returned or sold it shortly after.
On the turbo itself it's about 2 1/16" On the stock inlet it, intake side it is 2.5".

not to sound cocky, but on other forum site these are called "TIP"= turbo intake pipes. 
Abbreviation FTW

This is definitely a better option... Install was the easiest thing ever!!!!
I've heard ATP is horrible fitment...

Well, keep in mind you have a MAF sensor right before the coupling to whatever turbo inlet pipe you buy or fab. It has already been proven that the location of that sensor in relation to any bends in the path is critical (MS CAI recall).
Remember, when you have a bend, airflow is faster on the outer side and slower on the inner side. Also, it creates a restriction to the air inertia. (yes, air has mass) A 90 degree bend creates a greater velocity differential between the inner and outer sides of the bend and a longer period of that differential. A 90 degree bend will also have a greater resistance to the air inertia.
With that said, an inlet pipe similar to the ATP wouls have to turn sharp after the MAF, creating more disruption in the airflow through the MAF.
Think it through a bit before you go build your prototype.
Most people don't know that my first prototype was exactly what you are talking about. It was a 2.75" version of the ATP. I got backfires all the time and stuttering off and on. It was not a good design. To mate with any aftermarket or stock intake system and introduce a minimum disruption in the arflow, a smoother transition should be incorporated. That is what led to the final design in my final prototype.
Good luck and keep thinking!
Nicely explained for us newer guys here, like me. I understood, maybe wrongly, that turbulence to be able to disrupt the read at any maf sensor and the flow should be smoothed out before and after the sensor, to a certain distance in relation to the pipe diameter as much as possible. Working with fluid pumping systems as an electrical guy i learned a little bit about some of the flow theory involved. i am still learning. I was looking at my stock unit recently. I realised with a better performing turbo; I will need this piece or one very similar, along with the exhaust manifold upgrade. good work in theory and product!
Yea i understand all of that. That why i was planning on locating the sensor on the end of the straightest run of pipe (if you can get my horrible discription) I am an ASE certified master tech and i'm pretty creative, but also sorta a budget type tuner. I can't see spending 1500+ to get a front mount, cai and turbo inlet. Knowing howmuch parts are marked up and what it really costs to produce these parts it is just silly to pay that much.
