Draxa
Draxas is currently doing R&D on the headers for the 3 they will be out in september. They are one of my sponsors they are also coming out with an exhaust. The headers for the 3 will not be street legal in any application because they are directly connected to the primary cat. Which replacing the header would make the car non street legal. Also the plastic on the headers help with keeping the engine and engine bay cool which is a plus for performance.

Hmm That is some good information I'm really new to the tunning world and I never knew that replacing the headers would make the car non-street legal. Is this just for the Draxas application or will any replacement header make the car non street legal. Also is the stock header made of plastic or is it made of some sort of metal and just plastic coated. I always kinda thought that the plastic would conduct heat. Nonetheless this is good information.

If you're talking about the manifold on the front of the engine, that's the intake, not the exhaust.
The factory exhaust manifold is metal and it incorporates the forward catalyst. Replacing it would be illegal because you would be removing emission control components (unless you add another cat downstream to replace it).
yeah cause if you have 2 cats and catback delets one and header delets another...that wouldn't be good. Most people will do both catback and header so it would be ideal to keep a cat and O2 sensors unless you want the car to loose power when the cel for bad cat efficency comes on. I'm assuming they already know this but just in case you might wanna shoot an email their way just to cover all bases. they are metal with a ceramic coating to reduce underhood heat temps. If they did the same thing they are doing for us they changed the fingers to spin the air into the collector. They also would be same DBL as stock so you don't sound like a civic hatch.
I held a C average in english....my posts are perfect compared to my hand writing. Perfect for a doctor. yes the O2 sims would make the car think it's there and you cauld always holow out a cat and slide it over the pipes for visual inspection(laugh) I had a friend who borrows my obd II reader cause whoever did his setup did'nt do the sim right and his car goes in and out of "Limp Mode"
OK, I guess I'll tell everyone...
Hey guys, just a heads up, go swing over to Auto-EXE's website and drop them an email about the header they will be releasing this October... you won't be sorry you did (hint: VERY chrome and twisty). It should retail for $1200 shipped to the US (ouch!) but is expected to yield 11hp at 6300rpm and 9.5 ft/lbs at 5000rpm. But that's just the beginning, if used in conjunction with their existing exhaust and intake systems, the total package is estimated to produce a 26hp gain throughout nearly the entire RPM curve. I already have the intake system (wow, see pic), the only thing that sucks is that you almost have to sell a kidney to buy the stuff. I'll keep you posted on future J-spec parts. Also, they have a set of power folding Japan-only mirrors with control switch available from the parts department at Mazda Japan for $300, I got mine for $175 from a wrecked Axela in Yokohama, JP. Happy hunting!

Yeah! I love the soundclips Auto-EXE gives you, the trick is when you're navigating a Japanese site and you don't read Japanese... Really wicked parts though, the intake I ordered from them looks like something out of a Le Mans prototype car or something, and the shifter knob is very JDM tuner style.
oh yeah Da 6: I'm in Orlando, Florida

Sup NIM and welcome to the boards. From the sound of it, you have a pretty kick ass ride being created. YOU MUST POST PICS! of these items installed. Do you have any? Hopefully you do and we can stop fantasizing about how they might look. Thanks!
Remember that JDM spec'd 3's and 6's are different then US spec'd...thus you can't look at gains the JDM variants get, and assume they'll be the same for the US spec. They'll always be less gains on our end due to the lower compression, and emissions equipment.
This of course also means that you can't go buying JDM equipment "expecting" it to fit. Of course most of it can be modified to fit, or may fit, but don't assume its going to fit, always leave time and money for modification. This especially applies to any type of body kit and/or engine mod. (JDM spec doesn't have 5 mph bumpers)
