Seeing as the stock ECU really runs the engine quite rich, have you guys experimented with intake/exhaust mods with a better air/fuel ratio? I wonder if some of the lack of results could be attributed to an over-rich mixture - as in the engine can breathe better, but it's just drowning in fuel.
Considering that VERY significant power gains have been made in tuning the mixture, I wonder how that, coupled with a good exhaust/intake, will pan out.

We are aware that the ECU was tuned by Mazda to run rich to protect the catalytic converter. Yes, we have reprogrammed the ECU to run a leaner mixture, and the power results improved at higher RPM.
It seems that Canzoomer has made progress with his development of a ECU piggyback unit, congrats to him for having a product out so quickly. It is apparent that he has extensive knowledge of the technology behind the programming and software.
Although this technology is new to us, we have made gains in understanding the ECU and the software. My personal knowledge of this area is fairly limited so I must consult with Jim Mederer for the answers to these questions. It seems that he can absorb this stuff like a sponge, and he must then present this info to us in a manner we can understand and relate to you guys!!! I will proceed cautiously on how I respond to ECU related questions; I do not wish to misspeak.
Don’t worry, once Jim starts to feed me more information and we have a better understanding of the workings of the ECU, the information floodgates will open!

Can anyone tell me which aftermarket manufacturers specialize exclusively in exhaust components? And which manufacturers design and build their own mufflers?
Thanks

Borla, MagnaFlow/Carsound, and Flowmaster specialize in manufacturing only exhaust components, however JIC-Magic, Greddy, HKS, and several other companies do make their own mufflers and exhaust piping, but also produce lots of other products.
Why do ask?

Mufflers are obviously the most restrictive element of a cat-back. Manufacturers who don't design and manufacture their own mufflers are limited in their ability to build systems specifically tuned for a particular vehicle because they are buying universal (usually Magnaflow) mufflers. This may explain some of the discrepancies mentioned.
Borla designed a muffler that is exclusively used in our cat-back for the RX8.

I for one am just astounded that we have 2 people from such highly respected companies, Jim Langer and David Borla, who are so willing to come on here and answer questions in such an open and frank manner. kudos to both. i don't frequent other boards so i don't know if this kind of thing happens elsewhere, but i sure as hell glad it happens here. rest assured when i am ready to buy some more power for my car i will be coming to you folks. thanks!

David, this a off the subject, but I have friend interested in a Borla exhaust for a 2004 Dodge Durango with a Hemi. Is anything in the works for this truck? I e-mailed your R & D department, but never heard back. Any info you might have would be appreciated. Thanks.

Jim: Perhaps you can buy a Canzoomer piggyback unit, just to see some of the potential gains the other products might give. A chasis dyno would pretty much give us and exact figure!

Did anything ever come of this?
My understanding is that back in late 2003 or early 2004, Borla was looking into developing headers for the RX-8; but, having just checked the Borla web site, I did not see such a product listed (though that could certainly be my own deficient search efforts!!!). Did anything ever come of such development work?

Racing beat for tranquillity, or you can head for expansive JDM stuff like RE-Amemiya's one if you got lots of sleeping bucks, be carefull, the Knight Sports header is just trash, got one and it's quite similar to chinese products...

I went ahead and purchased the Racing Beat header. But im a bit skeptical about the mid pipe, with all that jazz going around about check engine lights is there any other options out there that wont throw a CEL? For now im thinking to just keep my borla cat back and install the racing beat header and leaving the stock cat and res..open for advice

I do not live in USA, can't really tell you more about products but i would suggest a sport cat if you do not wanna risk a CEL, the trick is : i know there's a lot of those pipes producted in US, but i don't know where you can get it, and of course i don't know their names.
You should find everything you need on the pages with "research", or some peoples will tell you the best stuff for your use/will. ^^
