Que pasa amigos
I have to take my car to emissions testing. My CEL is on since i have test pipes. I dont feel like installing cats just for this one day. SOOO here are my questions:
1) if i use a handheld OBDII scanner and delete the codes, will the car pass / will they see this?
2) is there any computer software to clear the code with?
3) if i unplug the battery and drain the power so that everything resets, will they be able to tell that the code was once on?

I did a quick Google search for you and here is just about anything you need to know about an emission test in Maryland..............
VEIP General Information
What is the Right Test for Your Vehicle?
How a VEIP Test Works
To Help Your Vehicle Pass
Maryland’s Vehicle Emissions Inspection Program is Working! Your Vehicle Emissions Inspection Improves Maryland’s Air and Water Quality!
By having your vehicle tested, you're playing an important part in Maryland's successful and ongoing efforts to clean our air and water, creating a healthier Maryland for all of us.
Although there are many sources of pollutants which form ground-level ozone, automobiles and light trucks remain the major source here in Maryland.
By making certain our cars and trucks are properly maintained in accordance with manufacturer recommendations (the whole purpose of the VEIP inspection), vehicle owners can be assured that we are doing our part, along with industry and government, to keep Maryland a clean and healthful place to live.
For more information about motor vehicles and air pollution, please check the Maryland Department of the Environment’s website at www.mde.state.md.us.
What is the Right Test for Your Vehicle?
On-Board Diagnostics (OBD) Test
The On-Board Diagnostics (OBD) test is required for:
Model year 1996 and newer passenger vehicles and light duty trucks.
Model year 2008 and newer heavy duty vehicles up to 14,000 pounds.
The OBD test uses a scan tool to connect to the vehicle's On-Board Diagnostics computer. The connector is usually located under the dashboard.
The system is checked to determine if there are emissions control components that are failing which may cause the vehicle's emissions to exceed allowable limits.
Make sure the amber-colored OBD "check engine" or similar warning light is not illuminated or the vehicle will fail the OBD test. If the light is on, you should see your dealer or repair technician before coming in for the test.
If the vehicle has had recent repairs that required the battery to be disconnected, drive the vehicle in a normal manner for one week to reset the emissions monitors before bring the vehicle in for the OBD test.
NOTE: The vehicle cannot be tested if the shift indicator is not properly aligned or if the driver's door is not operational.
Idle Tailpipe and Gas Cap Test:
The idle tailpipe test is required for:
Model year 1977 - 1995 passenger vehicles and light duty trucks.
Model year 1977 - 2007 heavy duty vehicles up to 14,000 pounds.
Model year 1977 and newer heavy duty vehicles 14,000 - 26,000 pounds.
The vehicle should be driven at highway speeds for at least 20 minutes before the test to warm it up.
The vehicle will fail if the exhaust system has holes or leaks that prevent a valid exhaust sample from being taken.
The vehicle will fail if the gas cap is missing or leaking, damaged, or the wrong cap for the vehicle.
The vehicle will fail if the catalytic converter is missing or damaged.

Reset the code, drive your car for about 50 miles and then check for codes, if no codes show up you should be good to go.
If you wipe the code, and you retest for codes, it will show that the car hasn't had enough time to check over all sensors and will give a NOT TESTED reply. that = FAIL! they will tell you to come back after driving it for a week for retest.

My friend just took his '04 s2k to get MD emissions, he has an invidia catback with a stock cat. He wasn't running a code, but they did visually inspect the underside of his car with a mirror. The guy said he would've failed if he didn't have the stock cat installed or if the stock cat was damaged, even if the car wasn't throwing codes.
Can anyone confirm this?

They do a "safety check" under the car. I believe they do this to make their insurance company happy. They can no longer clearly see cats no matter what they say, a lot of new cars have cats located in weird spots you cant see. so to flag a car or fail a car that has a hidden cat will cause all kinds of problems.
I hardly doubt you can see the stock cats on a 350Z I'm not sure if the S2000 has it midway down the exhaust but some of the newer hondas have the cats located right on the manifold, plus a few mid section pieces that also look like cats.
Sounds like the guy was trying to push his power around.

I just had my emissions done on Friday. The mirror is in fact a "safety check" to look for gas leaks or pieces hanging off your car. I asked the lady while she was doing it.

I am supercharged with test pipes with defoulers but throwing all kinds of codes. I cleared my car with an ODBII reader and drove for about 15 miles (luckily no code was triggered yet) and passed the test. I still dunno how though. Cuz even though there was no CEL, but when I plugged the ODBII reader in, it still said I have a code. My recommendations is to go to the emissions station that I went to. It's the one in Silver Spring, MD off I-29. People that work there were mad relaxed. I was supposed to have to pay for late fee and they forgot or didn't even charge me that. I still dunno how I passed...
If you need more time just reset the codes and go in. They will tell you the car isnt ready and to come back. That will by you some time. If not its only 15 dollars extra.
