RE: cali spec
HERE YOU GO MAN: Here is a quote off of 3sx:
USE THE ATTACHED PIC AS REFERENCE FOR WHEN YOU LOOK UNDER YOUR CAR
The top pic is the stock FED SPEC, The next pic down is the 3sx downpipe for fed spec cars, then the next is stock CALI SPEC, and the last is 3sx downpipe for CALI Spec. Don't really focus on the 3sx stuff unless you plan to purchase one of them but yea just compare yours with the stock CALI SPEC and stock FED SPEC to figure out which one you have....
Hope that helps. Peace!

Which NA downpipe do you need?
Federal-Spec versus California-Spec
The distinction of Fed-Spec versus Cali-Spec actually has nothing to do with where you live or where the car came from - they all came from Japan! ;-) It has to do with emissions laws and how they changed over time, and the difference actually is in what year they are...
Federal Spec: As a general rule, all of the 91-93 non-turbos are federal-spec, have only one main catalytic converter between the downpipe and exhaust, have only one O2 sensor mounted just before the main cat and after the flex section, and the downpie connects directly to both exhaust manifolds.
California Spec: 96+ are Cali-spec. These cars have small "pre-cats" immediately off the exhaust manifolds as well as the main catalytic converter, and have 4 O2 sensors. This pipe connects to the pre-cats, and includes the necessary O2 sensor plug on the front part of the pipe. The 3SX pipe kit includes a O2 plug to plug the hole in the rear of the pipe by the main cat.
94-95 Cars: The 94 and 95 cars are mixed between Fed-Spec and Cali-Spec so you need to check before ordering to determine which model you have.
TIP! Determining your Pipe: We recommend that you check your undercarriage to see which downpipe you need before ordering. An easy way to check is look for the O2 sensor. If it is back in the middle of the car just before the main cat, you need the Fed-Spec pipe, if it is right under the oil pan of the motor and you see the bubble of the front pre-cat, you need the Cali-spec pipe.

RE: cali spec
Read the white label under your hood. It will say something about complying with California or US / FED standards for XXXX model year. If it says California, you have California emissions. If it doesn't say California- you have FED emissions.
