Right from the linky:
Major Differences
1998
5. In 1998 WS6s had single outlet exhaust (all others had duals)
12. 1998-1999 LS1 cars had a smaller throttle body cam, which caused the throttle to open to WOT faster than 2000+ cars
13. 1998 cars had 28 lb fuel injectors from the factory
14. 1998-2000 cars had a larger cam than the 01-02 cars
15. 1998-1999 cars had more restrictive exhaust manifolds
16. 1998-2000 cars had an LS1 intake with EGR
18. 1998 only LS1 blocks had a much smaller cylinder sleeve that only tolerated a .005" hone
19. Last year F-body to use the old 15.5 gallon steel fuel tank.
21. Only year LS1 F-body to not contain the famous GM black box used in the event of an accident to record up to 5 seconds of pre-crash data
24. 1998 cars have a completely different PCM from 99+ cars
1999
1. 1999-2000 cars switched to 26 lb fuel injectors
2. Cylinder heads and valve covers redesigned to have center bolts instead of perimeter bolts. Other than that, the heads were the same.
3. Redesigned cylinder sleeves that allowed for a small bore, up from .005" in 1998 models.
9. Switch to larger 16.8 gallon plastic fuel tank to meet new emissions requirements
13. Water temp gauge was redesigned to work basically as a dummy gauge and only show an overheat condition.

i think it comes down to more of a personal preference.
my 99 ss has small 26lb injectors, the older style steering wheel without the radio controls, zr1 wheels, more aggressive stock cam...
due to the wheels, the steering wheel and the cam, i wanted the 99 over an 02 i had my eyes on. i figured i was going to use hptuners to shut off all the emissions stuff and upgrade the injectors for nitrous anyway.
98's have issues with knock sensors picking up false knock.

Wait. Stop dragging the 99's into this. i'm ok with there being prejudice against the 98's because of the computer tuning "issues," but don't start on the 99's too.
I like how any time someone starts in on 98's they will always pull out the fact that they're the only ones with working temp gages.
Also, I'll point out that 99 had hugger orange, which is -- as everyone knows and agrees -- the best color of Camaro.
The long established LS1Tech bias/prejudice goes:
Best: 02-01 (LS6 intake and better clutch hydrolics
)
Good: 00-99 (had EGR and LS1 intake
)
Bad: 98 (computer tuning "issues")
It was asked a couple times: Ebony (black) is darker than Charcoal (gray). Ebony was offered starting in 00.
These posts come in waves. Six months to a year from now, there will once again be a bunch of multiple-page posts about this.

Hate to disappoint you too, but no, that's not different, that's options! It's called a power Steering Cooler

Again, Options are involved. My car was sent to SLP, therefore, I had the SLP Dual/Dual Exhaust. Sodo you call that Factory? i DO, CAUSE I HAD NO CHOICE ON IT. But my two other 98 SS 1LE Counterparts have the single exit. Not sure how many WS6's were sent to SLP in 98, but I know Some SS's were!

And to be honest, it actually cracks me up how few of you truly know all the differences, or atleast the ones that matter
Injectors are good on 98's, Heads suck, Heads are okay on 99's, but jsut okay. LS1 intake is a major down, oil consumption is an issue with most, not all!!! but most. Oh man, LS6 blocks... Some, i repeat, some 02's have them. No, they don't make more horsepower, but they support more! Traction control!?!?! My 98...It doesn't exists, I have no traction, just ABS on my rear-end. Many, many, many other differences, jsut cracked me up people started talking about the negatives on interior. I mean, are you serious?
Now, to actuallyanswer the question of how 02's, not 00-02's, but 2002's are better( Imean, if you're gonna be picky, pick the best). You must tlak about numbers, and specific causes of those numbers. Take a 98 and an 02 with same mods, tune them and dyno them. You wil see a modest 15hp difference at the wheels usually. Reason for this is, LS6 Intake, 241 heads, compared to 98(806) heads, 98PCM Parameters compared to many more 02 PCM Parameters for tuning. These are just the most common reasons an 02 will pound for pound outperform a 98!
Hope that helps

The WS6 was done by ASC from 98-02. The only WS6's to go through SLP were the 96-97 cars.
ALL 98 WS6's came FROM THE FACTORY with the single exit exhaust.

I really don't see the '01/'02 as "the best". They have downsides as well, depending on your priorities. I see all years as equal, with each year having some positives and negatives over the other years.

98-99 Camaros got better looking stock wheels IMO

EDIT: As far as debating performance benifits of the different years, its all a bunch of BS because there were not any signifacant differences between the years. Except for the 98 computer being a hinderance in wild setups.

I had a 98 and it ran fine, 13.0 with a lid, otherwise completely stock. It would go 12.0s on a 245 nitto with a baby cam and all the usual bolt ons.
If you're going to leave the car stock, just get an 01 or 02.

No, you get the **** out. Since when is a 10whp difference really going to amount to ****??? All kinds of different factors effect performance at the strip, including M6 vs A4(most of the time the A4 will be faster in et with street tires since its real easy to hook and drive). Other factors include type of tires(a cheap *** kuhmo all season will go up in smoke while a BF Goodrich KDW will dead hook every time, and I know this from experience).
I've beat on multipe 2000-2002 M6 bolt on fbody's at the strip. They might have had a higher mph, but I was usually one to four tenth's quicker.
When you start modding, year doesn't really mean ****. The factor that really matters is A4 vs M6 and the intended purpose of the car(A4+stall+slicks owns at the strip), while a M6 is better suited to auto-x or road racing.

I was told to steer clear of 98 LS1's strictly due to either the harness or the PCM.
I can't recall the exact reasons why, but peeps here told me this.
I ended up with a 2004 GTO Ls1 instead. Mine was a retrofit into a 78 Camaro.
Speartech did the mods.
