are headers worth it for our car?

I just checked, and there were 80 non-Calif spec 1999-compatible Max engines and 6 Calif 1999-compatible engines available in New Jersey. That doesn't sound like a majority to me.
Searching California for Calif-spec engines shows about 3-to-1 in favor of non-Calif-spec engines available in California.
I stand by my statement - Calif-spec engines are clearly in the minority - everywhere I looked on the coasts - California and New Jersey.
Not that this matters in the least, but I confirmed what I thought I was seeing earlier.....

Both my parents cars are California spec and I know numerous locals who are california spec. I am just saying that you will find more fed spec cars in the midwest because there are less people and less pollution while in the northeast and california, it is way overpopulated and there are wayy more emissions so therefore, california spec cars were sold in that state. This is what Dave B told me when I first found out my car was Cali-spec. I too thought that California-spec cars were only sold in CA but i was convinced otherwise.
Calif-spec cars could be sold anywhere, and probably got shuffled around to meet demands for inventory.

headers
my car bought here in jersey and im a cali spec. imo the headers are worth it definitle feel the difference especially aound 3 to 4000 rpm. also has a nice tone with little to no drone. cattman is the way to go if you are goin with headers.

to that.My '99 is Fed spec.

Coming soon around september we will finally see a before/after run of y-pipe vs headers on a 4th gen, I have offered a free install on headers, all he has to do is pay for 2 dyno runs.
Only on 2000 cali spec's and 2001's would you need headers to eliminate both precats (although you could do a fed spec front exhaust manifold conversion in either case). 2000 fed spec's are just like A32 fed spec's.

I probably should have worded it like this: ......and on a 5th gen adding headers/y-pipe is a very very very close comparison to adding a y-pipe to a 4th gen due to eliminating the pre-cats
I bought my 2k1 SE max brand new in Canada and it's cali spec, headers make a difference over the Cattman Y-pipe, I think on my 2k1 the difference are like 9-13 HP+ but I know those number will climb once the Vortech V2 is on. My 2 cents

But on a 99 cali-spec car the precat is only in the front header. The back header for all 4th gens, regardless of fed/cali spec were the same I think? Correct me if I am wrong. Therefore if one can get their hands on a junkyard front header and a y-pipe plus an 02 sim...they are basically fed spec.
Once and for all:
1999 Fed spec = both precats eliminated with y-pipe
1999 Cali spec = requires headers to eliminate front precat (or fed spec front exhaust manifold + o2 simulator)
2000 Fed spec = both precats eliminated with y-pipe
2000 Cali spec + all 2001's = requires headers to eliminate front precat (or fed spec front exhaust manifold + o2 simulators)
1999 Fed spec = both precats eliminated with y-pipe
1999 Cali spec = requires headers to eliminate front precat (or fed spec front exhaust manifold + o2 simulator)
2000 Fed spec = both precats eliminated with y-pipe
2000 Cali spec + all 2001's = requires headers to eliminate front precat (or fed spec front exhaust manifold + o2 simulators)
