I'm not sure if the O2 sensors work on the 2k5+ but I know they do on my car (2004) but I rather not use them if I don't have to. The idea is to have a clean exhaust and no CEL. i'm in the military and though there are no required emissions testing in TN, who knows where I'll be in a few years. Maybe a faulty O2 sensor? who knows? I'm going to run the car for a few days and reset the ECU again.

here's another question: Are the O2 sensors and their heaters running on the same voltage? If not, crossed wires may explain my problem.

No idea what to tell ya guit... any luck fixing it?
-----------------------------------------------------
Had a chance to go on a nice drive today on the highway(s) around here... This is the most dramatic upgrade I have done to this car. Bar none! Still not throwing an o2 code, but I'm going back to Mike tomorrow to get the o2 sim installed.
I'll get a rev video up tomorrow.

Took me 3.5 hours to do headers...... oh and it was my 1st 6th gen. I think I can cut the time down to easy 2.5 hours now that I know what kinda goofy wrenches I need to buy for that damn EGR pipe- I still got scars on my right arm.
No need to drop the subframe. I can build, tune a new TL motor in a days worth of work... and thats including removing the old engine, building the new one, assembling the heads and then putting it in the car and crossing your fingers as you hit it to 7K 1st run out. Been in the car game for quite some time
Enjoy the mod Jeff.

Figure I should post my rev video of the headers installed in my '04 (Greddy SP2 + Cattman y-pipe)... Yes, the mufflers have since been cleaned. lol

Just thought I would let you all know, Brian says they are no longer on back order.
" We will have several sets on the shelf from this batch...... I’d be willing to extend the backorder discount for any orders placed by end-of-day Tuesday."
So anyone ready to pull the trigger on some headers, now is the time to do it. Best way to contact him is directly by phone:

Could you elaborate on what you mean about o2 sensor issues.
I mean is it what we been discussing already about o2 Sims
and extending o2 sensor down the y-pipe?
03-26-2009, 11:13 AM
#136
There are no O2 sensor issues as I have discussed ad nauseum. You extend the O2 sensor wires and you will have no check engine lights relating to the headers. Period.

If you have no cats, get a dual-channel simulator and you will be good to go.

If you have a cat on your y-pipe, just extend the two rear o2 sensors behind the cat... you will most likely have to have 2 bungs welded on your y-pipe to do this.

I guess I'm just making sure that no one else with an 05 or 06 with 5AT has any CEL before I dive into getting these. I've heard the O2 simulators don't work on 05/06 5ATs. The place I want to get them installed at keeps telling me that I would get one since a fellow orger with a 5th gen kept having his CEL on even after they extended his wiring with O2 sensors, granted that's a 5th gen. Just looking for testimony from an 05/06 5AT that's all.

From what I understand... the o2 simulator option won't work with '05+ because the sensors are wideband. So Presence, you may have to get a cat welded to the y-pipe, and get two o2 sensor bungs welded in past the y-pipe... how far, I'm not sure... Deus could help with that.

we have a guy on nissanclub that has a se-r 6spd with cattman headers + y-pipe(catless) and o2 sensors and is somewhat successful with the o2 sensors. he is throwing 2 codes: P2A03 and P2A00
I didn't get an answer about what those codes pertain to, but he had went 600 miles without a cel and then it randomly came on. he is working out some issues with his clutch and said he will address this problem when he gets to it....

I'm assuming the CAT that is included in the Y-Pipe is a 3-way CAT?

btw, headers installed today on my 06 3.5SE Altima....extended secondary o2 sensors behind main cat on the y-pipe and about 20km later the SES comes on....just waiting to find out what the codes are but apparently it's related to the secondary o2 sensors....not sure what the problem is

all wiring is fine...basically all o2 sensors were extended for clearance from the headers so I don't think that is the issue...how would you know anyway?

No I mean how would you know if they are extended properly....I know deus was the test pilot....

Does anyone know if you will be able to pass emissions with the main CAT only on the Cattman Y-PIPE?
04-08-2009, 11:24 AM

We use a good, EPA-approved 3-stage cat in our y-pipes, and a 3-stage cat is meant to adequately clean up the exhaust without precats to back it up. These y-pipes have been selling for 16 months now, and we haven't heard from anyone who hasn't passed emissions with a Cattman y-pipe (w/ cat). Keep in mind that most states do not actually "sniff" the exhaust anymore on late-model cars, they just plug into the computer to check for error codes and may check visually under the car to make sure the main cat is there.

Hi guys! First time i post here! I need help lol!
I installed my Cattman headers & B-pipe last week (racingline y-pipe was installed few months ago), i kept the stock exhaust; I'm now catless and i used o2 sim dual output.
Here pics of my modified harness and location and ziptied them for test :
Everything was fine until today, i got 2 SES codes :
P0138 : O2 oxygen sensor circuit high voltage (bank1, sensor2)
P0158 : O2 oxygen sensor circuit high voltage (bank2, sensor2)
I also notice the led on my sim is blinking fast... do you know if it's indicate some errors? What can i do to fix it?!?
Thanks!!

well here are my codes:
P2A03 and P2A00
what a pain in the ***...it's reading problem with primary o2 sensors? I thought this issue was fixed. the wiring was perfect as well.
oh well

what I'd like to know is why deusx did not get any codes to date....what did he do so differently?
04-09-2009, 09:11 AM

Deus didn't do anything differently - he followed a standard procedure and did it correctly.
Everything was buttoned up tight with no leaks (as with any installation, always go back and tighten all fittings after 2-3 days of driving), the wiring harness extensions were done properly, all 4 O2 sensors are functioning properly and he's following the time-proven method of locating the secondary O2 sensors behind a working catalytic convertor.
Successfully replicating this procedure will get the same results.

I'll add that Deus is hardly the only one with a trouble-free header installation. We've heard from many customers (and their comments appear in the Maxima and Altima forums) who have had the same experience after a successful installation that included locating their secondary sensors behind a working main cat.
I can't say for sure, but there seems to be a pattern of issues coming from the use of O2 simulators in 05+ vehicles. There was a concern from the beginning about sims working with the new O2 sensor technology Nissan deployed that year, and some of these primary and secondary sensor-related codes may confirm that.
