Exhaust, cats, CA emissions

Does anybody know if a visual inspections (specifically exhaust/underneath car) are required for CA smog?

Will our cars (stock) with a primary cat removal pass CA smog?

Can you reset the CEL just before smog testing and not fail on that point?

Thanks much.

Yes, there is both visual and sniffer tests + an OBD read. Doubtful that without the primaries, it would pass. No, resetting the CEL will not pass since when they do the OBD read, it will likely show that your o2 sensors are not passing.

If you go to a local, reputable shop to get the pipes and install, they will likely have a "guy" that can pass the car if you hand over a few bills. This is even easier if you opt for an HFC option rather than catless.

Realistically, CA emissions are bogus when compared to what other states get away with...not to mention the carbon footprint for electricity (burning coal), overseas shipping, etc. An M3 HFC x-pipe is pretty guilt free in my opinion...

Unless you "know a guy", I don't know any other way around it. You'll probably have to put the exhaust back on and put the stock tune back in.

It's nice that the newer cars now have 6 years before the first SMOG test.

FYI, starting this year, tailpipe emissions testing in CA is no longer required for vehicles 2000 and newer.

http://www.smogtips.com/new-smog-law-AB-2289.cfm

Quote:
Set to begin January 01, 2013; Model year 2000 and newer vehicles will no longer require the tailpipe emissions test portion of the smog check process. AB 2289 will require late model vehicles be administered the smog check's visual and functional tests only.

The implementation of AB 2289 is expected to reduce the time and cost of the smog check. The program will now take better advantage of a vehicle's OBD II technology by eliminating tailpipe testing and instead using the vehicle's own OBD II emissions monitoring system.

This new smog test system is already in place in 22 other states. "This new and improved program will have the same result as taking 800,000 old cars off the road, also resulting in a more cost effective program for California motorists." said ARB Chairman, Mary D. Nichols.

Currently California's smog check procedure requires all vehicles undergo a tailpipe emissions inspection to measure harmful pollutant output from the tailpipe, a visual inspection for present and properly installed emissions components, a functional test to insure the proper operation of various emission components; and as part of the functional test, an OBD II computer diagnostic check.

Under AB 2289, the tailpipe emissions portion of the smog inspection will be eliminated for 2000 model and newer cars, trucks, vans, and SUVs.

Background on the OBD II system - All vehicles imported into the United States as of 1996 have had to be equipped with an On Board Diagnostics system referred to as OBD II. The OBD II diagnostic system is designed to monitor all aspects of your engine's emission conditions and report this information to a central database within it's computer. This information is processed and checked against the computers pre-determined values for various input levels and performance patterns.

If any problems are found, the computer will determine whether to alert the driver or not. If a decision has been made to alert the driver of an emissions problem, the "Check Engine" or "Engine Malfunction" light will illuminate on the vehicle's dashboard. In more serious emission conditions the computer may even begin to rapidly flash the "Check Engine/Malfunction" light indicating to the driver, that the vehicle needs immediate diagnosis/repair attention.

AB 2289 now requires the smog test inspection to rely on data from a vehicle's own on board emissions computer to determine the vehicle's harmful emissions production as opposed to using a smog machine to sample the vehicle's emissions output from the tailpipe. This design is expected to reduce the cost of equipment at the smog station, reduce the amount of time it takes to smog check a vehicle, and reduce the cost of the smog inspection to the consumer.

People with our software shouldn't need to flash back to stock.

How about exhaust volume? Do they measure it at all these days?

Will have to move back to CA and I'm wondering if my Eisenmann race will be causing me trouble to register out of state vehicle.

You won't have to worry about that other than the fact that some shops won't mess with cars with ANY mods whatsoever, legal or not.

The no sniffer law has NOT been put in affect yet.

They will start mid year this year. So far it's still sniffer and visual.

We have certain areas of the state that don't rewuire it. Maybe I will change my address.
