Hood, spoiler, wheels, and whatever else the person ordered on the car from SLP would be on it.

Try a search and you'll find more answers than mine.

Welcome to the site.

The SS is differentiated from the Z28 model in that the former was sent to SLP for a composite high-rise spoiler and a composite ram-air hood along with a few other small touches. Additionally, all SS models "qualified" for additional SLP content, such as: upgraded exhaust (explained below), Auburn High-torque differential, chrome wheels, SLP grille, car cover, key fobs, etc etc. There were roughly eleven SLP options in total, give or take a few, and the extent of the SLP options on the car would be included on a sticker located on the passengers side door jamb. That said, many SS Camaros were just that: a base SS with no additional SLP content. Thus, the sticker that I just discussed in brief would be absent.

A few more differences in the Z28/SS models: the Z28 was rated at 315HP for 2002, whereas the base SS model (without SLP power enhancers) was rated at 325HP. Many believe that there are little or no differences in the power between a stock Z28 and a stock SS. Also, the gearing was slightly different in the models All 6-speed models have 3.42. All SS Auto models have 3.23. The Z28 A4 models have 2.73 or 3.23 (the latter being optional, extra cost).

The exhaust packages available from SLP on the SS model and their subsequent bump in horsepower ratings is outlined below:

335HP Dual-Dual Exhaust
335HP CME Exhaust
345HP Dual-Dual Exhaust w/ Blackwing Air Lid
345HP CME Exhaust w/ Blackwing Air Lid

The Blackwing Air Lid was ONLY available in 2002, and therefore the 345HP package was also only available in this last year of production as well. CME stands for "Center Mount Exhaust," and you'll recognize it immediately if the car has it. The "Dual-Dual" system has four exhaust tips, two on each side. The stock Camaro SS exhaust is basically just two smaller sized chrome exhaust tips on each side. If you give us a picture we can probably determine your setup from looking at the exterior, assuming it's mostly stock.

One more thing pertaining to the model variations: as mentioned above, you'll want to confirm it is a true SS model by looking at the Regular Production Option (RPO) sticker on the drivers side door jamb, specifically noting the presence of: WU8 (SS model). Y2Y is often interpreted to mean additional SLP content was put on the car, yet its inclusion is very inconsistent with regards to this.

^what he said. sometimes a different exhaust can be purchased from factory so some had more power than others. btw if i were you i'd find a 01-02 SS instead of a 99, better heads with the better intake on it

When I was looking for mine I atleast wanted a 2000 b/c of the body colored side mirrors, unless I had found a hugger orange one.

Just a nit, I'm pretty sure the Z28 HP rating was 310 in '01-'02 (up 5 from 305 in '98-'00). SS/WS6 HP ratings were always 15 more than non-SS/WS6 models (w/ the exception of additional SLP options on SS models).

Another nit, no difference in heads on the '01-'02s. HP increases these years were attributed to the LS6 intake manifold. Only change in heads was between '98-'99 when rocker covers went from perimeter bolts to center bolts AFAIK.

2000 got the 853 heads, 01-02 got 241 so what you talkin about? last i checked on my 2000 SS i had 853's and the stock cam size was 198.86/209.25 .498/.497 LSA 119.45 and every-time i raced my buddies 01 T/A with his stock 241 heads and his stock cam was 196.37/208.72 .464/.479 LSA 115.92 he would beat me by a car or more, unless he had a total factory freak i'd say the difference is in the stock H/C combo from GM. both cars are A4 and we had the same headers, same LS6 intake and same gears.

I was going by what was documented here. However, upon further investigation into head casting info here, you are correct that there was a head casting change in '01. However there doesn't appear to be any difference in the port volume, valve size or chamber volume of any of the LS1 heads, 806/933 ('97-'98 perimiter bolt covers) or the 853 ('99-'00 center bolt) or 241 ('01+) heads. Not sure what the difference is between the 853 and 241s, possibly the elimination of EGR provisions?

In any case, there doesn't seem to be any difference in head design that would positively affect performance. Certainly, any difference you observed could be attributed to production variances or "driver mods". As has been documented numerous places, the 5 HP rating increase in the '01-'02 F-bods, let alone the 15HP rating increase of the SS/WS6 over the base Z28/Formula/TA isn't reflected in real-world track times. Some '98s can crack the 12s stock, while some '02s have trouble dipping below 13.5 stock. For all intents and purposes, performanc-wise, a LS1 f-bod is a LS1 f-bod. Some are freaks and some are dogs. But you won't be able to tell which is which by going just by it's production year or head casting#.

The WS6 was the only option to get the taller box. The Z28, SS, Formula, Trans Am and Firehawk all recevied the standard box.
