So does my 99se cali-spec have no potential???
i've been reading alot here about how cali-spec's have a bunch of useless junk in the exhaust and that fed-spec's are so much tighter than cali-spec.
what potential does my 99 SE-L Cali-Spec MAXIMA have? or do I HAVE TO CONVERT TO FED before my maxi can enter dopeness?

It has about the same as any other 4th gen. JWT has a program now, there for it lacks nothing. Treat it like a 5th gen and get some real headers, get some sort of VI, and something to tune with. Youre set with just a few mods.

Idk why everyone keeps saying that there's a pre-cat in the headers. I have a 99 cali spec and yes i do have 2 cat's. One AFTER my headers before the y-pipe and one after the y-pipe between the rear exhaust. I'll be changing both of those along with the y-pipe...

Sticky: 4th gen FAQs (READ ME! PLEASE! READ ME!)
What are the year to year differences on 4th Gen (95-99) Maximas?
1999 -
On CA emission 99's Front pre-cat built into header, two extra oxygen sensors to monitor pre-cats (total of 4), Swirl valve in intake to improve emissions. Special aftermarket Y-pipe required and only 1 pre-cat can be removed.
basically, this left me w/ the understanding that the pre-cat built into the header cannot be removed, and that there is 2 pre-cats. Is this sticky wrong? I want to know because I want to 'maximize' my 'maxima' naw mean.

The sticky is correct. I'm just telling you what i have on my car. My mechanic showed me both of my precats. I told him i have one in my headers and asked him if it's difficult to change it. He said why would you change your headers when you pre-cat is sitting right after them...I was in total shock but i do have 2 pre cats which i can clearly see under my car.
#8
There is a thread about converting the front mainfold to a fed spec. The car was dynoed with both the cali spec front pre cat and a y pipe, then the stillen up pipe was added with a fed spec front maninfold. There are very very minimal gains, and you do lose some mid range power. If you want to be cheap about the conversion buy the SS autochrome headers and y pipe.

In a Cali spec car, by putting in a Cali spec y-pipe you eliminate the pre cat near the catalytic converter. You do not get rid of the pre cat that connects to the header.
picture of how the Cali Spec Y-pipe looks and the remaining precat.

Check the 5th gen forum out for some good info on headers/fed conversions. All 00-01 are like a 99. Most of those guys just shell out the money for Cattmans or Hotshot headers. They are a far better design over the SSAC, but much more money.
