Can I use an oem catback from a 5.5 gen on my vq30 5th gen? Any issues at all?
What about the cat, is it the same? Are the positioning of the o2 sensors the same?

Thanks

 

I know the muffler will work but not sure about the mid pipe. Sorry.

 

I beleive its anything after the y pipe that is the same,not sure about the rest of the system

 

the 2000 fed spec has an o2 after the cat, all the others do NOT

 

So you are saying the OEM B pipe & OEM muffler from a 2003 fedspec will NOT bolt up to a 2000 Maxima fedspec?

 

ALL 2002-2003s are CALI spec.

If you have a FED spec 2000, you will need an O2 sensor bung after the main cat, which is a pretty easy job for any shop. That is of course, unless you get a b-pipe made for a FED spec 2000.

All b-pipes, rear sections, cat-backs, etc for 00-03s are interchangeable and will bolt up just fine. Just check to see whether your 2000 is FED spec or not for the purposes of figuring out whether you need the O2 bung.

 

Well it was built for Canada so I am assuming it is fed spec. Is there any way to tell for sure if it is?

 

Pop the hood and look on the sticker, if it says it meets california emissions then its cali spec, if not...fed spec

 

Is this sticker aroud n the VIN plate?

 

Look in the FAQs.

4 O2 sensors = CALI

3 O2 sensors = FED

 

Hey,
Instead of getting a bung welded in place, is there any reason why I can't just stick an old o2 to plug the hole up? Just curious...

 

yes you can...

 

Hmm...

Well, one other question then....
Do 4th gen and 5th gen o2's use the same thread pattern? If so, I would just plug the hole with one of my old 4th gen o2s....

 

yes they do....

 

interesting...
...why dont more people do this? is it because the o2 sensors protrude into the path of the exhaust too much, hence restricting airflow?

 

this is a funny thread. just plug it with a short bolt, probly better anyway, i guess if you dont have a bolt then the O2 is just fine.

 

first, why dont u tell us what you're exactly getting? cuz from your original post, i can't tell if you're implying stock or aftermarket exhaust parts...

i can answer one part however....if you're getting STOCK parts off a 5.5...then the bpipe will have NO hole...so you must bring it to a muffler shop to get one welded...

if you're getting aftermarket, it MIGHT come with a hole...my 5.5 bpipe came with 1 hole specifically designed for fed spec maximas...I never used it, but it came with one...

 

I am getting a 2003 OEM catback....ie muffler and B pipe. I want to put this setup on my 2000 fedspec without having to do any modification other than bolting it up.

My understanding for the above setup, is that the 2003 catback will come with one extra bung which I will have to plug if I install on my 2000, correct?

 

P.S....I just realised I was mixing up the term "bung" & "plug".

 

Do you guys have a diagram for the placement of o2 sensors on 2000 to 2003 maximas like the one below for 4th gens?

 

your 2003 oem catback will NOT have an extra bung on the piping...but it will bolt up with no problem...you have to figure out where to plug in your 2000 FED SPEC o2 sensor...

 

btw, why are you getting an OEM 2003 catback? your reasoning better not be for performance gains...becuz it won't gain you anything...

 

I'm not quite sure why this is so hard to understand.

 

hes been a member for such a long time...

i realize 4th gen and 5th gens are different cars regardless...but to ask "can i use an o2 sensor to plug up the hole?" is just ...

 

OK, I am getting mixed answers here. One person says the 2003 has 4 o2 sensors. I am assuming 2 before the cat (y pipe, header area) & 2 after the cat (in the b pipe). And another person says that the 2003 will not have an extra bung. How many bungs does the 2003 catback have total?

I am not doing this for performance gains, I want to switch my aftermarket b & muffler back to stock for noise reasons.

About using the o2 sensor to plug a bung, I was asking because I have never done this before, and it seems almost like a "too good to be true" solution, so I thought I'd ask first...

 

^^^^^ There is your answer. NO CALI SPEC CAR HAS AN O2 AFTER THE CAT.
Did I clear it up enough for you?

I had a bung welded in once and the shop put it in the wrong spot, so I plugged that hole with an old O2 and had them weld in another bung.

 

bottom line is...YES, it will fit completely fine....however, YOU WILL have to get an extra bung welded onto your 2003 catback...in order to accomodate the o2 sensor that your fedspec has behind the main cat...PERIOD

if you ask any further questions, then you should not be driving a maxima

 

cool, thanks for the clarification guys.

maybe it is time for me to switch to a corolla.

 

My bad, I should have read your initial post and not bothered asking the same thing multiple times
