Hello All:
It's that time of the year again, and DMV is looking for a Smog Certificate. I was wondering if anyone has passed the test w/ a cat bypass and single inlet/dual outlet B&B setup. Debating if I'll have to crawl under the car and throw the cat back on. And, if this will even ensure a pass. I'm not sure how ozone friendly the B&B exhaust is. Any comments would be most appreciated.

Cheers!

 

If the inspector is a stickler on the visual, the absence of the cat will mean a fail regardless of the emissions.

My 78SC passed with pre-74 exhaust.

You did n't say waht other mods you car has, carbs, etc., but if the OEM fuel induction system I would get an gas analyzer and check the output prior to taking it in.

And be sure you don't take it to a pass only station, but someone who will run a pre-test. Otherwise your car may turn up to be a gross poluter simply because the fuel it adjusted too rich and you will be required to have it tested by a Gold-Shield station.

Good luck.

 

I'm curious. Has California revoked the thirty year rolling exemption, so that only cars from '75 and older will ever be exempt from testing? Also, what happens there when a "gross polluter" pre-'73 car is detected by one of the roadside stations?

As I say, I'm just curious. I live in a free country, known as Massachusetts, and I'd like to know what it's like elsewhere.

 

good question...I would like to know as well since I have a 1975 (Passed NM emmission last year), so will my car be exempt from now on? Going to Germany in a couple months and the car should pass all the inspections there as well...does anyone know what they look for?

I have an 80SC with a bypass and a Bursch exhaust. I remove the bypass (6) bolts and I always pass the test with the Bursch intact.

 

25 years and older don't need to be smogged(?). It's either that, or cars prior to 1974 are exempt.... i only drive an 83, but see i've seen 75 and 76 bmw 2002 going super cheap a.) late model "square" tail lights and b). they are just past the cut off.

 

Last time I checked, it was a 30 year rolling excemption from semi-annual checks, or model year prior to 1974. They keep talking about repealing the 30 year thing.

The Historic plates are 25 years, and car of historic significance, which supposedly also excempts you from yearly tests. There is a thread on Pelican about them here:

1973 and prior cars are exempt, everyone else has to get smogged. There isn't a rolling window at this time. The last smog bill set the window to start rolling again in '03, I believe, but you know how things change. There was a bill last year to push the exempt year back *down*, so '73 would not be exempt any more -there is a LOT of money to be made in getting early cars smog legal.

If you get busted with a cat bypass, a couple things happen. For one, you get sent to the Smog Referee for a through rectal example of your car by Mr Badwrench, and you actually incur a monetary fine. I know this because the last time I was at the smog ref I read all of the pamphlets in the waiting room.

I just went thru the ref process to get my 3.6L legalized. The process is not too bad if you've taken the time to have your papers in order and everything on the car the way it's supposed to be. Even then, I had to fight a little, because their docs showed a 1990 engine having a check engine light, even though I had factory DME manual pages to the contrary.

Thom:

Do you know what the laws are regarding installation of a later year engine with the subsequent emissions equipment? The "newer" engine would definitely give a power increase, as well as, have more modern emissions equipment. This should be a win-win.

Cheers,

 

I've heard of some people plugging a fuel injector and using a cylinder as a big air pump. Semms like it would reduce the emissions by 1/6th. Not that I would do this, just wondering if anyone else had heard of anyone doing this.

 

I have a 1992 911 with only 20,000 miles on it and it failed the California dyno check last time I tested. I just barely flunked but flunked. This after getting the car really hot by running it to redline in the first 3 gears a couple of times on the way to the test site to "blow it out" as they say. I was completely shocked at flunking and wondered what to do as the car seemed to run fine. I changed the sparkplugs and oil retested and passed. That's how sensitive the Ca test is. <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />
