What ever the cost of the cat is. The 2 options I am looking at the Magnaflow 99659HM and 59956.
The 99659HM is a OBDII complaint 400 cell heavy metal cat with a 5" body and the 59959 is 200 cell metallic cat with a 4" body. The 400 cell cat sells for $120 and the 200 cell for $100. I am leaning towards 400 cell since it has a higher capacity and more surface area.
The 4" core on top and 5" core on bottom.

So I'm at a little over 150 miles on the new downpipe/midpipe and it's been trouble free so far. No check engine light as of yet and I've gained about 2-3mpg city. I notice the smell associated with going catless sometimes but it's not overpowering for me.

400 does look shiny though =)

If you offer a catted pipe I'd just do the 200cell. I don't see a point on putting on a 400cell. Might as well leave the stock one on there. Thats just my opinion. Dynos may show otherwise. Turbo cars love to breathe.

side note: will you be making the second o2 sensor after the cat? and on your next models will the second bung be located on the down pipe region incase someone wants the option to swap from full race to the cat?

Yes the OBD I core is less restrictive per inch however you have to factor in cross section as well. If you have a 200 cell cat that is only 1" in diameter it wouldn't very good. The factory cat and OBD II cat are 5" across which has a cross area of 19.6 in^2. The OBD I cat is 4" in diameter and has a cross area of 12.57in^2. The 5" diameter cats have 43% more cross area compared to the 4" diameter cats. What does this mean? Not only does the OBD II cat flow around the same as the OBD I cat it also has a higher capacity. Higher capacity allows for more abuse, especially for turbo applications. However it is up to you guys I don't warranty cats only workmanship and welding.

The factory cat is 625 cell, OBD II cat is 400 cell and OBD I is 200 cell.

In your experience, I am curious to know what the performance difference may be between between the larger cat vs. no cat versions. Are they that restrictive?

It sounds like you have done this for a lot of vehicles. I share your concerns with a smaller cat melting or self destructing is some way under more spirited driving...I have seen this happen before with aftermarket hi flows with the RX-8.

i guess if needed i could go to a muffler shop and have them do a straight pipe for me that is swappable i just would prefer a premade peice i could buy later on..

We can make you a mid pipe with and without a high flow cat. Figure around $300 for a catted mid pipe. Basically everything from the clamp back including a high flow cat. I wish there was enough room for more slip fits connections so that you could just swap out the core. However there is only around 1/2" of spare tubing after welding in the high flow cat.

ill probably go with the catted version for now and then bug you for the free flowing version later =)
so is 720 for the full setup w/cat going to be the final price??

which core did they use? (type 4, 13 14??)
Ok guys, let me explain this particular air-to-water setup for you since I'm a member of that russian RDX fans community.
That setup was not the first one. Now they start to use this kit more often than before cause they were able to play with all those parts and figure that out.
First of all, this set up is a custom kit. It consist of:
1) core element;
2) front mount radiator (intercooler);
3) water pump (Bosh, dont know which one exactly);
4) hoses and fiitings;
5) antifreeze (engine coolant).
Antifreeze has been used due to obvious climate conditions in Russia instead of regular water.
Core has been mount on top of the engine instead of stock IC using some custom adapters and brackets.
Radiator has been placed in front of both stock radiators (AC and engine radiator) with no changes made to bumper.
There are a lot of technical issues with that setup. The core element you can order online from fozenboost.com . But some cut and welding must be made additionally to fit our stock piping.
The radiator element has to be not very big since it will be placed between bumper and AC condenser and need to have some space between this element and AC condenser itself. I'm still wondering why they don't use a fan for that radiator to increase air flow between them.

If either one if effective at holding the exhaust assembly in place and allows for (somewhat) easier/reliable mounting and dismounting, then it makes no difference to me which is used.
