Need to borrow 05+ Maxima for header test in SoCal
Correct. You also need the O2 sensors relocated past the cat in order for the ECU to know the cat is working as is detailed elsewhere in the thread.
lol
Everything looks good so far as CELs go. The last step in our R&D process will be to have an expert (I don't want to drop names) to review the Cipher datalogs that Deus has been recording on a laptop. Just want to be sure that there aren't any bad numbers buried in the data that could pop up as a CEL under some combinationi of unusual driving circumstances.

wait so you're saying I NEED the Y-pipe to have the cat in order to install the headers ? I can't have it with out the cat ? if in case i will get the racingline Y pipe and throw the Cattman manifolds on ? and if i'm fine with no cat y-pipe do i need the o2 simulators ? please let me know before i make a final decission on what exactly do i want to get , and also Brian told me 5 weeks ago that in 5 weeks the headers will be out for sale ? is there another 5 weeks we're looking at ? thanks

Glad things are moving along!
After this phase... what are we looking at for the AT headers?
Thought I would let everyone know that the development phase of this project is complete. Deus's car has shown no problematic engine codes during the 2 months the headers have beein on the car, and the "globally-recognized expert" who was kind enough to look over the Cipher datalogs says all looks very good. He even thought we might be able to pass the CARB certification, although I have no plans for that at this time.
Whew, finally! I want to take this opportunity to thank Deus for working with us on this project. His help has been invaluable.
We couldn't set prices until now because the cost of steel and other ingredients are a moving target. Although they're a bit higher than expected, here are the introductory retail prices, followed by prices reflecting a maxima.org discount.
Headers only, AT or MT version, no EGR port (07/08 Maximas) - $599.99 retail, $569.99 w/ org discount
Headers only, AT or MT version, with EGR port (04-06 Maximas, 05/06 Altimas) - $629.99 retail, $598.49 w/ org discount
Y-pipe only, AT or MT version, NO cat and NO "extra" O2 ports - $379.99 retail, $360.99 w/ org discount
Y-pipe only, AT or MT version, WITH high-flow all-metal cat and NO "extra" O2 ports - $579.99 retail, $550.99 w/ org discount
Y-pipe only, AT or MT version, WITH high-flow all-metal cat AND two O2 ports behind the cat - $599.99 retail, $569.99 w/ org discount
Header/Y-pipe system, AT or MT version, NO cat or "extra" O2 sensors - $939.99 retail, $892.99 w/ org discount; add $29.99 for EGR port
Header/Y-pipe system, AT or MT version, WITH high-flow all-metal cat and NO "extra" O2 ports - $1139.99 retail, $1082.99 w/ org discount; add $29.99 for EGR port
Header/Y-pipe system, AT or MT version, WITH high-flow all-metal cat and TWO O2 ports behind the cat - $1159.99 retail, $1101.99 w/ org discount; add $29.99 for EGR port
There are special header prices for customers who purchased a Cattman y-pipe prior 01 November. If you already have our y-pipe, your price for headers is determined by subtracting the price already paid for the y-pipe from the three piece system price. In other words, if the system price is $893 and a y-pipe was purchased earlier for $380, the price for the headers would be $513.
IMPORTANT notes:
1. 04-06 Maximas and 05/06 Altimas require an EGR port on the back manifold and the 07/08 Maximas do not (prices vary).
2. Because installation of the headers requires removing the precats, its necessary to make the secondary O2 sensors happy (because they monitor pre-cat function) to avoid related error codes. In a 2004 Maxima, this can be done with an O2 simulator or by installing a main cat in the y-pipe, followed by two O2 ports for the secondary sensors. This is not confirmed, but it "appears" that an O2 simulator will not fool the ECU in 2005 and later Maximas and Altimas, so installing a cat and two O2 ports in the Y-pipe may be necessary to avoid a CEL.
3. We are offering a retrofit service for installing cats and O2 ports in Cattman y-pipes that have already been purchased - send the y-pipe back and we can install cat and/or O2 ports (exact price not yet determined, will be $200-250). We also have cats ($139.99) and O2 ports ($5.99/each) available if a customer wants to have it done locally and save the shipping. This service is limited to upgrading Cattman y-pipes, but we'll consider doing other brands IF there's enough room for the cat and O2 ports.
4. These are introductory prices, and unless steel prices go down there will need to be a small increase early in 2009.
We will begin production with a run of 20 header sets, which should be ready in about 4 weeks. Since there's quite a bit more demand than that, we'll start taking early orders now. Give us a call at 800.759.9920, we're open 9-5 MST, M-F. We will take all the normal order information, but there will be no payment before the parts have been produced.

OK, FWIW, I just heard from someone who is pretty knowledgable that it may be possible to use O2 simulators with an 05+ Maxima, so who knows...
An 05+ Maxima owner with a catless y-pipe is just going to have to pick up the sim and try it outwhen they install the headers.

Ok I have a few questions.. I spray nitrous on my Altima SE-R and as a result of doing that for almost two years now the car is running like strait up a$$. I dont recall the exact code it is throwing but it says banks 1 and 2 are running lean. Its not my MAF, its not coil packs or spark plugs and I tried adding fuel with my SAFCII and the two primary sensors dont react to it at all so I've come to the conclusion that they are shot as a result of the spray but thats ok. I will buy new primary sensors when I get my headers in. I know it was previously stated that all sensors have to be extended but I have a few detailed Q's so here they are...
1.) About how far do the primary sensors need to be extended?
2.) How far do the secondary sensors need to be extended? I think Dues said he did
42" and it was a tad bit long so correct me if I'm wrong...
3.) Will the primary and secondary sensors require the same gauge wire or will they
be diffrent since the primary is a 5 wire and the secondary is a 4 wire?
4.) If I were to buy new bosch universal 02 sensors for my secondaries, would they
work fine as long as they are a 4 wire just like the OEM ones?
5.) Is it best to solder all the wires and shrink sleeve them with wire loom on top of
that?

I can help with #1...
The headers have bungs for the primary sensors. No need to extend them. As for the secondaries, there is a bung for one of them... you could either extend them both as Deus did, or get a dual channel o2 simulator and install as follows:
http://www.o2simulator.com/discus/me...tml?1108216235
Fully connect the sim to the loose o2 sensor as per instructions, and tap the white signal wire into the sensor that's in the bung and you are good to go.
And #5... sure, why not! Definitely solder and sleeve them!

Its best to measure for the amount needed to extend. It also depends on the routing of the wire too. Its always better to be too long rather than too short. I would highly recommend solder and sleeving the wire.
