Had a box waiting for me when I got home






ohhhhhh it's shinny




But....the SP2 is supposed to be only for the 95-96 so why is there an o2 bung on the B-pipe?

i had that on my sp for my 97-99 but i had to plug it since i have no o2 sensor back there

I30tMikeD

iTrader: (8)

oh, maybe I have it backwards then? But I could swear my o2 sensor is on the cat

doesn't the o2 sensor go there?

You are correct. 95-96 should have the O2 in the cat.

My 97 has the O2 sensor in the b-pipe, that looks like it was made for a 97-99, but one thing I don't understand is why is it crooked, like on a angle, doesn't make sense.

Your missing the point...of course it is for an o2 sensor. But if I indeed was shipped a Greddy SP2 for a 95-96 Maxima (which is the only SP2 they make) then it would not have a bung for the o2 sensor on the B-pipe since a 95-96 maxima/I30 has the o2 sensor on the cat.

I wonder if they sold me a 97-99 SP and not an SP2? But then the B-pipe wouldn't be stainless and it looks stainless to me...I think?

Here is the sticker on the side of the box and a better pic of the B-pipe..does it look like full SS to you?

95bkackmax18s

iTrader: (11)

so your i30 is a 95-96 and it should be in the cat. this one is in the b-pipe. its full ss, so its got to be a sp2, did they change something? im learning, so sorry if im not making sense.

NYC_Maxima97

looks stainless steel to me, why don't you give them a call and tryo to clear it up with them. Did they ever make a SS SP?

You got the correct part. I too have the SP2 and I just sealed that bung with a bolt.

On my sp1, there is a o2 bung as well but there is a bolt that goes in the bung when it is not used. Don't know if u also recieved the bolt as well. I would call them.

That's a tiny resonator, hope it's not too loud. Btw, I just got my Cattman catback in.

So all these 97-99 guys are worried ordering the SP2 because there is no bung for the o2 sensor....but there is a bung for the o2 sensor. Greddy is confusing me.

fusionx21

I'm confuse with the 02 sensor plug in? Is that bung suppose to be bent to a side like that? Correct me if am wrong but I uselly see it straight on other exhaust?

you got ur SP2 already? oOo...i'm gonna e-mail steve from SWA. once i get it i will confirm with you regarding rear o2.

well...from your picture it looks SS to me. also, on the box it says "sp2" so it seems right. if i get mine like that i, would just get a bolt and seal that spot...

good luck installing it mike

to help you other people understand better, here's the O2 chart for A32:

The SP2 is on back order for a month, but I called every online tuner shop that carried it for a maxima and found one that had 2 in stock. I didn't want to wait a month or more.

i remember reading about someone else having this same situation...also not sure why they did this.

hey mike if u dont want it it will fit my 98 max

I ran into the same problem for my 95 SE with my SP2 system. I ended up plugging the "diagonal" hole in the pipe and I also reused the stock cat. From what I hear, the stock cats flow beautifully as compared to aftermarket cats anyways.

Wow, an org member from Aurora......thanks but I think I'll keep the exhaust.

chicago max98

iTrader: (6)

after u have it installed can i get to hear it i need one too thanks

I30tMikeD

iTrader: (8)

Sure, but I also have cattman headers so it won't sound the same as it would with an aftermarket or stock Y-pipe.

krismax

iTrader: (15)

My cattman b-pipe had a bung in the b-pipe also.
The bung is a + think about it, put a racing pipe in place of the cat and plug the o2 into the b-pipe bung.

I don't know why the SP2 would be like that, Mike, because your logic is impeccable on this. I think that Greddy may have the applicable dates wrong in all of their advertisements. I just find it odd that no one pointed out this discrepancy before now...

Anyway, let us know how the install goes! What exhaust do you have in there currently?

bruteMax

Post up vids when you're done with the install Mike. I can host. I'd like to see/hear what the SP2 sounds with the Cattman headers/y.

And yes the SP2 for whatever reason comes with an extra bung, at least mine did too.
