I bought my '07 350 last July and it did not have a cat when I bought it, straight pipe from the turbo to the tip. Is there anything I can buy to simulate a cat so that it will pass the visual inspection?

 

doin my own 6.0, I run a vegistroke on my truck right now (wvo burner). It smokes more at idle and taking off from a stop than diesel. You are right though, if it is put to a sniffer, it will come up with ZERO emissions.

 

I personally walked into a smog shop today and asked what they are looking for as far as diesels go in CA. It is a visual inspection only, EGR cooler and Catalytic Converter. That is it, they don't even have to work they just have to be there, Cat can be gutted, EGR can be blocked off, but the components have to be on the truck

 

Here is something I found on another sites forum. I just copied and pasted what was there.

CA 2010 Diesel Smog Law
I just wanted to send out an update to all Californian CTD owners on the latest this FINE state has to say about smogging our diesels. Any updates are welcome as it's hard to find some reliable information. The best information seems to come from the BAR site. This thread on the Cumminsforum has an excellent overview. 2010 Diesel Smog Inspection for 1998 and up/under 14,500 GVW Trucks - Dodge Cummins Diesel Forum

I wonder if this will promote aftermarket exhaust manufacturers to sell str8 piped "cats" that are made to look like cats but are perfectly gutted.

I've pasted it below:

Hear is the latest updates from the California BAR.

Hear is what they are testing for:

-Visual Inspection of Smog Components
-OBD II Check with scan tool, "three monitors must run to completion"
-Visual Smoke Check, "most likely at idle and 2500 RPM"
-Probably EVAP (Fuel Cap) Test

Much of the confusion on GVW has come form the DMV's website, but the BAR website is more accurate as they provide the update training for the smog techs and distribute licences and so on. Slide 6 of the above BAR powerpoint presentation for the Smog techs says 14,500 and under GVW will be tested? The DMV website below is wrong in stating less than 8501 lbs:

Vehicle Registration for 2008

Colorado is said to be doing the same thing along with other Green states like NY and so on. Just look at the retrofitting for the Big Rigs! Every state that currently smogs gas cars will eventually smog Diesels. It looks like I need to move to Hawaii or Montana

 

dang.. link no longer works. Ill find it again and see if I can get more info regarding the diesel smog laws.

I added a 4" turbo-back exhaust to replace the 3-1/2" stock exhaust. I also replaced the gutted stock cat with a MagnaFlow cat.


The MagnaFlow is 1/3 the cost of the stock cat (in oem condition). I understand folks' desire to un-restrict exhaust but my situation is that the truck carries a living space on the back (EarthRoamer XV-LT) so emissions are genuinely a consideration although I don't have to meet strict emissions controls in my state. I didn't discover the gutted cat until the installation of the new exhaust. I had to cut the forward clamp off the stock cat to fit the downpipe extension properly (as the installation instructions indicated) for a proper fit.

I did ultimately buy the MagnaFlow cat and modified it as with the stock cat to fit the new exhaust.

...so if you need a gutted stock cat but don't need the stock clamp connection on the forward end let me know...well I have the clamp from the MagnaFlow too if you really need the whole thing but it would have to be welded together...

thats soooo cool, if thats whats truly going to happen only a visual inspection. I can gut the cat pretty easily, I've already gotten all of the items needed for the egr delete, maybe I'll just use what I need from the kit and modify my egr cooler and put it back on. I'm thinking of a stainless plug about 1/4" thick welded inside of the cooler to stop the exhaust from going there, update my oil cooler and clean my turbo while I have it all apart... the truck runs so perfect right now I don't want to touch it.. but you know how it go's, we cant stop playing with things. hey mdub what is vegistroke? a vegi oil I'm assuming, does it need to be pre heated to use? and how is the cost per gallon? and does it produce as much power? thanks guys.

 

My guess is a Vegistroke is a Powerstroke runnin WVO

 

I didn't have time to read all previous posts, so sorry if I am redundant:

I just had my truck smogged last month in GG. They did a visual inspection only; i failed. That weekend I did a full EGR delete. I had to go back and put the cat on, and passed. The truck has nothing stock, tuned, and all = ok. In 2 years we'll see what the 'dictatorship' says we need to do to pass. No tailpipe sniff this year, maybe a 'snap' test to visually inspect for black exhaust. Just detune the truck so it doesn't 'roll coal'. someone mentioned that they did have the OBDII hookup to check for a tuner. Do not have a tuner exposed or visible during the test.

 

Good to know.I was going to bypass my egr and gut my cat, the truck runs clean in normal driving, if I floor the throttle it smokes abit for a few seconds.. but snapping the throttle up to about 3k with the truck in park produces no smoke at all. the truck was running great.. I knew I should not have said anything about how my truck runs the other day.... because now I think that I have jinkst my self. it was running perfectly fine. until this morning. went to start it and all it did was shutter and try to run.... like not enough fuel???it ran perfect last night when I shut it down? what a POS. I hate electronics on cars. well we'll see what happens this weekend?
