I wanted to know if I need to do anything before I take the test. Its a 2000 Prelude with AEM Cam Gears, AEM CAI, DC headers, Apexi V-AFC, AEM Fuel Regulator and Fuel Rail. Will need to take anything out? Or will I be ok? Thanks!

 

what happens if you fail the test?

 

If you still have your catalytic converter on and have working O2 sensors you shouldn't worry about anything, the emissions test will test the pollutants coming out of your exhaust, and if you have an OEM cat on your car you emissions should be fine reguardless of engine modifications. Just be worried if you go to an emissions test with a test pipe on or possibly a high flow cat.

 

Your 2000 prelude already needs a smog check. I guess outside of ca things are different. I just got a smog check done and had to put back my stock intake because my old aem intake doesn't have a carb #. You might want to get a pre-test to see where you stand now. Also, make sure the cat is hot. I dropped my HCs in half w/ a hotter cat converter.

 

Very true, your cat needs to be around 500-600 degree F, before the catalyzing effect begins to take place.
