I guys, I just got my first Duramax. It's a 2006 GMC Sierra 2500. I got it from the auction in MO. My buddy owns a dealership, so he was able to get it for me. He took it to get it smogged, and it did not pass. This is what the smog report said in the comments.

EGR removed, no EO for air intake,no catalytic converter, no EO # for performance tuner, Black smoke during BAR Snap Test.

ALSO: Missfire

So i did not know that the truck wasn't stock, nor did my buddy.

If i knew it has this stuff on it, I would have taken the Tuner and KNN intake off before the smog. If anymore can help with some other issues, that would be great. Thanks guys.

AFE, Banks both warranties for life, I’m pretty sure most of them do.
At first I bought 2 AFE filters no downtime cleaning, drying and oiling.
Over the past 12 years AFE has sent me 2 more filters to add to my collection.
I’ll have 3 dirty ones, then I’ll clean dry and oil all 3 at one time ready to go when needed.
My other 4 vehicles non turbo gassers 3 are K & N, one is Banks system with scoop, I have 2 filters for each of them ready to do a quick swap out when it’s time.

Like I’ve already mentioned monitor your MAF g/s if possible, then you’ll know when it’s time to clean your filter when it’s dropped about 5 g/s.
If the numbers get high enough to set the P0101 code then it might be time to replace that filter, of course under warranty.
Every tuner I’ve dealt with has asked me what brand filter I’m running, concerns with to much airflow.

K & N makes the Banks filters, but to Banks specs which has different media and more layers.
K & N shuts down production making K & N filters when they need to produce filters for Banks.

“Good Luck”

I have an Edge tuner on mine and when I used to have to have my truck smog checked I'd just set it to stock and it passed just fine. My EGR and everything is stock though. You can also just unplug the tuner where it ties into the harness and unplug the wire in your fuse box under the hood (should be a red wire). Edge tuners after something like 2008 meet CARB standards. If you want to be sure it's up to date you can send it to them and they'll update it. I sent mine in because it was an early 2007 and didn't meet CARB and WA State goes by the same standard. They updated it and sent it back. Cost to me was postage.

Thanks for the reply, I'm going to contact them tomorrow to see what i have to do so they can update the tuner. If i can get a carb sticker for it, I'll reinstall in before the smog. On the smog paper work, them mentioned that the tuner did not have a carb sticker, along with the KNN intake, however, i have been working with KNN to get that sticker, i may have it by this Friday.

Wow man, hate to state the obvious but.......
You gotta know what you're buying if you know it's going to have to pass a smog test. Or least your buddy should have known if he's in the business. Make him sell it and go find one that fits the bill. You need to be looking for one that's already current on the smog test. Fixing the one that's been deleted is going to cost. Just buying all the parts is going to be painful enough not to mention paying a shop rate for someone to mess with it until they get it to work right again. That truck better be something special or hope you already stole it in the first place if you go down the road trying to bring it back to stock emissions. Good luck and wish you the best!

When we saw the tucks images, they never showed a picture of under the hood. The Upgrades were great to have, he took it to get smogged the same day it arrived from MO. Once it failed smog, thats when i knew what was under the hood. Now, i have to turn it back to stock in order to register it under my name. Its still under is companies name.

With my truck I know, extatically what I explained.
The cat is for show but if your emissions does sniff testing and your truck already stinks it'll still stink with this cat.
Mine was in the shop for trans lines replacement, when I went to pick it up the whole shop was full of my truck running and stinky exhaust with the Magnaflow cat on.
I turned around, went home and loaded up my stock cat to have him put it back on, 5 years of suffering with the stink was way to long.

This is all I did to get rid the stinky exhaust, no noticeable changes with EGT's or power.
BTW I hate CATS.
And BTW deleting the EGR and tuning for deleting the EGR has nothing to do with stinky exhaust.

If your around Phx anytime soon your welcome to try mine

Thanks for the info. I havent been in Phx in years. I'm going to try and located a stock exhaust here in Ca for the smog, and ill throw on the 4" right afterwards. Finding a stock exhaust here is almost impossible.

Dan,
He is in the Demokratic Peoples Republik of Kalifornia. There are No counties in that state that do not have smog testing, it is a State Law.

True. But I'm the biggest patriot Mexican you'll ever meet. Born and raised in Kern county. WWG1WGA

i Was able to get a free KNN filter. KNN warranties their parts for life, so they sent me a new filter, but they made me purchase the heat shield in order to get the carb sticker from them. I need that sticker to be able to pass smog. they also sent some screws for free. I love dealing with them, they stand behind their product.

Their filter is still a terrible product and allows dust into the engine...

I would just disconnect it for now. Mine get's disconnected for a few days every two years when it's that time.

You don't need a whole stock exhaust. Just the cat piece. If you have an aftermarket down pipe, it will need a CARB EO number, but nothing after the cat is important.
I have 5" MBRP exhaust, no muffler. The stock cat and MBRP test pipe are interchangeable. Its just a vband at the downpipe side and a 4 bolt flange with a gasket to connect it to the catback section. These just get swapped every two years, quick smog, swap back, done.
You don't even need to drop the cross member like some people think. I have been able to snake it in and out many times with the cat can lined up with the engine oilpan and torsion bar. Apply a tiny bit of pressure outwards on the torsion bar and the cat just falls out.

Living where you do, just mosey on over to recycle road in rancho cordova. You can grab anything you want real quick. Worlds largest collection of vehicle recycle centers, pick-n-pull, etc.

Shameless plug, not affiliated in any way, but since we are talking about ordering stuff...

I highly recommend dmaxstore.com. Great prices, and wonderfully helpful staff if you ever have questions.

My Allison service package just arrived. Transynd + filter. Extra gallon for transfer case fluid change.

If your looking for stuff, I highly recommend them if you are local to Sacramento, you can pick up your order in shingle springs, short drive up hwy 50.

how does that help the OP register his deleted truck in the peoples democratic republic of california?

If you read, it is stated quite clearly how it is related. Troll much? JWC

Here is a recap since you apparently missed it...

He needs to buy stuff, quite a bit.
He is in the Sacramento area, as stated.
Dmaxstore.com is located very close to sac, and has great prices on some of the things he needs. He can pick it up rather than paying shipping.
I also mentioned in another post, where he said he was having difficulty finding a stock exhaust. I pointed him to another area near him that many people wish they had near them, recycle road in rancho cordova. I guess by your logic I should not have mentioned that resource either?? 'dunno;

no, not a troll. how does a good deal on aftermarket parts, in particular transmission fluid, help him restore factory parts? its aftermarket parts that got him in the place hes in now. Unless i have missed a whole section on there site, they do not sell factory equipment. If you pointed him to a place that sells used factory stuff, thats great, and probably does help. I like duramax store too, i just dont see how they would help the OP. A shameless plug would imply that you have a financial motivation to promote this brand, hence, not exactly helpful to the OP, and kind of a grey area on the forum as well.

First definition in google for shameless plug:

A “shameless plug” is a term often used on the Internet to refer to a time when someone tries to include (or “plug”) some information that helps advance their own selfish interests. And that information is usually a little bit off-topic.

Dude, you are a prime example of why I lurked since 2013 instead of having a massive post count. You cant help anyone without someone like you jumping in to be like this.
OMG you used the wrong word.
OMG, his post title said he needed help un-deleting his egr, it doesn't matter if he also asked about his ABS wires being chewed up, or his wheel bearings, which I also mentioned he could get at NAPA auto for about $80, guess I shouldn't have mentioned NAPA auto either.

He said his wheel bearing and abs sensor wire needs to be replaced, along with a long list of other stuff that isn't ONLY his deleted egr system.
He then responded saying that is cool he would make the drive for good service. He found it helpful.

You didn't apparently, now you are on here nagging about how appropriate it was for me to tell him that info. Really?

They sell some GM factory stuff, and some better than OEM replacements, as well as aftermarket.

What is hilarious, is I made a point to poke fun at needing to disclaimer everything to not get flamed in an earlier post in this thread, didn't take long.
@CaliDude, if you want any advice, or even to meet up some time since we are a town or two away, shoot me a DM. I promise I won't give you a hard time if you don't have perfect grammar, or recommend anything in passing that might be helpful, or talk shit about your K&N filter every time you mention it.

Im sorry that you feel that way. I dont feel like you needed to disclaim everything or anything, i was simply asking how that post pertained to the OP's issue. I still do not feel that it does. What it does do, is makes it look like you are affiliated with DM store trying to push there brand. Im sorry if i misunderstood what you were trying to get at, however that is how it reads based on the word choices you made. I also do not see how a CV shaft helps the OP. What i am not seeing on there site is anything in the way of factory exhaust, cats, and other components to restore the truck to stock, though i will admit they do appear to have the EGR valve and gaskets for his truck, though i believe he has already purchased those from ebay per a previous post.

I simply asked you to explain the relevance of your post as it pertains to the OP, and instead you come back with a bunch of attitude. Im sorry if you applied tone to my post in your head that was not there.

I will admit that my post may have been short and lacking detail that could have avoided this issue, for that i apologize. I do not think that asking you to explain how the post you made was relevant was wrong though. At this point from reading the OP's responses it sounds like he has sourced most of the parts for the truck excluding the exhaust.

To that end i would recommend looking to see if there is an intact exhaust system at a junk yard that could easily be put on the truck to pass inspection. At that point the truck would be legal to register, and that would either give OP time to source proper parts for the truck, or to hit a big pot hole, his choice. It might not even hurt to look on craigslist for someone wanting aftermarket exhaust, see if they will just trade you for there old factory hardware, or see if there's someone selling a factory exhaust.

The answers to your questions were in the thread already. He asked about stuff other than his EGR. I mentioned this fact in my prior post, but you seem to have missed that. You stated they didn't sell anything but aftermarket parts. I provided a link that proves otherwise, which you then took issue with and cited relevancy. Really?

Seems like you are just arguing for the sake of arguing dude.

OP I am sure didn't take issue with my post that certainly didn't hurt anyone.

I had also mentioned he is right next to the biggest collection of auto recycle and junk yards in the world, and named the location, but I am learning I should have phrased it like you "find a junkyard" rather than attempt to be helpful and provide details.

I made sure to edit the post in question to reflect your feedback however, and clearly explain why I was posting that post, even though the context of the thread should have made that evident. I guess you have to be real careful to only answer questions in the OP's first post and nothing thereafter here at duramaxforums. Lesson learned.

I stayed away because of all the posts by others complaining about the toxicity of this place. I recently made the decision to try and help out where I can. I am thinking I was on the right track the first time by staying away.

You may be right. If you run it like a dog in the dirt. I plan to run a Pre Filter On top of the KNN filter. I have sold KNN filters for over 7 years, and I love their warranty, and their customer service. Paper filters will and do clean more, but Im always on top of my filters and service. Im actually Very Anal about it.

Ive been looking for a stock exhaust for days, and i found a stock Cat in modesto, but i would have to weld it on. Im trying to find something that I can slap on, and slap off. Im going to call around recycle road to see if someone has a full stock system.

As a California resident, I feel your pain. I recently failed the readiness monitor portion of the test. All because the high idle/PTO switch was left on, which I never ever turn off because it turns the function off when not in park or the first time you hit the brake pedal.

Not sure where in Cali you are, but I am up just above Auburn in Norcal. If you run into any issues and are near, give me a shout. I have a tech 2 and know these trucks in and out. A few local shops call me if they run into a duramax stumper question.

I just saw this post while looking for resources for making my Texas LMM CA compliant, any chance you have time to speak with me about this?
Thanks,

DanT... bumbalard hasn't logged into the forum since Aug. 2020. The LMM platform was California compliant from the factory. You just need to install any parts that "may" have fallen off....
