Fastest Stock 93-97 Camaro Z 28
#2
i would assume 96, or 97 due to the 2 cats on it. And the fastest 1/4 is probably gonna be the one that ran closest to sea level with the best air, 13.8ish on an auto. Just guesses here though.

Then I will take it a step further Shoebox. Has anyone ever dyno'd stock 93-97 Camaro Z 28's with auto trans and found a significant different between years?

Yeah the earlier ones did sound a little better. Does that mean that my car originally had dual exhaust? Or 2 cats to a single chamber muffler?

I tend to think the reason behind the 2 cat setup was for emissions purposes. The 1995 California emission A4 cars had the same 2 cat setup that was used on all the 96-97s and it was still rated at 275 HP.
I think the the 10 HP difference for 96-97 was in tuning or just marketing hype, given 93-97s are so equal. A lot of people say the SD 1993s are the fastest.
Turbo Bob is really looking for real dyno numbers and not factory advertised specs. We all know how the factory advertised ratings on the LS1 were lower than actual.

I have never understood what the difference is if you take 2 pipes and Y them into one cat (93-95) or take two pipes that each have a cat and Y them into one pipe (96-97). They both go into the same single intermediate pipe going to the muffler, so where is the gain made? How do you get more flow out of the same pipe?

Thanks for all of the info. Just one thing what makes a lot of people think the SD 1993's are the fastest versus the mass air 1994 through 1997?

It is mostly the 1993 owners that say that, but it may be due to the amount of people that really know how to tune the SD system and get the best out of it. There may be more parity between the years now, because there is lots of tuning experience for MAF cars, too.

Also is there a big weight difference between the 93 through 97's?
I am a big fan of hardtop F Bodies. Do F Bodies with t-tops weigh more?

If even the single cat system was restrictive, then adding an aftermarket cat back would produce little, if any, HP gains (but it does add HP). I just can't buy the whole 2 cat extra flow scenario [= HP].
