emission testing

[thrasher324]

i have a rb25 but i dont know what i would have to do to pass emission. i was gonna get a cat on my exhaust but from what i heard aprently i cant put a cat onto a full titanium exhaust. which is what i have.

i dont really know the deal with obd1 and 2 but my rb25 is from a skyline gt-t so its a NEO version. help

hopefully your exhaust has flanges, if so, just bolt in a factory cat to pass emmissions, then put back in your test pipe.

your car will pass an obd1 tail pipe sniff test with a good factory cat.

your car will not pass an obd2 test unless you've wired the obd2 data link connector into the harness and you're using a usdm z32 ecu to run the powertrain....without any detected errors.

thanks for the response.
wouldnt the piping size be different if i tried to put a stock one?

the inner diameter of the piping may be, but the flanges should still bolt up. this is temporary, it's just so you can pass emmissions. once you pass, you can put your test pipe back in.
