Update from Jim
Got an email today from Jim. Things seem to be looking good for this project!
We're concerned with the configuration of the Mazsport unit with regards to potential contact with the chassis. They used our available presilencer and shoe-horned them into place the best they could, but they still needed to use a couple of spacers to allow additional clearance for a chassis brace.
We've already re-designed the two presilencer units to be more circular in shape, and one will be slightly shorter to allow clearance with the brace. (Eliminating the need for the spacers.) It will be a couple of months before we have the presilencers in stock, but once they arrive we can assemble these units fairly quickly. Hang tight, I'll post news on the site when I get more info.
Best regards,

So they completely redesigned the presilencers just for this application! Awesome.
Although that does now mean that we have to wait for them to get the new presilencers and then to make the actual midpipe.
I'll see how long I can hold out!
Great news however!

A few months probably means you won't be able to get this until the Summer assuming they don't have any issues with the redesigned silencers, other projects, a lack of funding, and that we don't slide into a full blown depression and start hiding cash under our beds.
Very happy that there will likely be a replacement next year for the DR - and that the replacement will hopefully be significantly improved over the MS in terms of engineering. Whether or not it delivers the same reduction in noise will be interesting to see.

Still waiting for a car in Miami so we can do the DR pipe. We can use any resonator you guys want. I prefer the magnaflo because they sound really good but it doesnt matter.

damn, RB isn't messing around! I might have to consider this since I don't think my RP supercat is going to last long with MM's AP tunes

Wow, I can't believe I just now found this thread. I have the Racing Beat midpipe and exhaust now, but I will definitely consider replacing the midpipe with this if the price is right I think it would be awesome if RB created some maps for their hardware on the Cobb AP as well, hint hint...

Anyway, I figured since RB has already done lots of testing with their own parts and that's the parts I have installed, maybe they could sell a locked version of a map like MazdaManiac does for a lot less money than the re-flash since I don't need to take out the PCM and ship to them, they ship it back etc, etc... I don't know if it would require me data-logging my car or not since I have all RB parts (ramair, intake, midpipe, exhaust) Maybe they could sponsor me since I have all their parts on my car

^What I was trying to say, is that none of the modifications they sell require any sort of a reflash to take advantage of.
Gross Oversimplification Time:
The only things that matter for a good NA PCM tune are the MAF reading, the wide band reading, and the AFR targets you have setup in your tune. The RB intake will not require a new MAF calibration. The RB header locates the wide band in a place that will still provide accurate readings. All of their other parts (duct, race pipe, exhaust) have no chance of affecting the tune. If you flow more air because of the modifications you've made, the MAF will see the increased flow and the PCM will inject more fuel in order to hit the desired AFR target defined in the flash. No change required.

BTW, don't flame me if I'm wrong, I'm trying to learn with every post I make
Doesn't less back pressure force it to run a little too rich without re-tuning a little? I know that it smells a lot more without the cat, some of that to be expected, but I believe it's running more fuel than it needs also. Anybody feel free to step in and correct me because like I said, I don't know this stuff and I'm just trying to learn

^No, 10 is way too rich. Generally 14-15 for light throttle/load is where you want to be, and high 12's to high 13's under heavy load if you're naturally aspirated. A race pipe should have no effect on your AFR.

It's good to learn though. I have tuning software from COBB but I haven't even installed it to look at what's involved. I don't want to mess with any of it until I learn what everything does. Are there any good books out there about that kind of stuff?
