I am sure we will start seeing high flowing DPF just like we saw high flow Cats come out. Hell was not ATS (spits) working on aftermarket DPF? Not much came of it. But is a start. We may see twin DPF.
Thinking out loud but maybe use something other than the engine to make the heat need to regen them.

25 years ago a cat converter cost well over a grand from the dealer, and aftermarket ones that flowed considerably less cost in the $300-750 range. Now today you can buy high flow cats that will outperform a stock one in flow by a large margin for under a $100. And back then people said cats would never be reasoneably priced so everybody ditched them, now today they are semi affordable and many are leaving them on or going to aftermarket units. It's no different here as the industry will drive and dictate what happens. A high flow DPF hasn't been readily available simply because it was so easy to just remove it. Hopefully now this will change.
Even though I don't agree with this move by EFILIVE as there ARE instances where deleting the emissions could easily be considered legal, I also understand the kind of heat they are probably getting from the EPA(and the EPA won't let something like details get in the way of there end goal). So I understand why, and can agree with why they are doing it. BUT it still doesn't mean I have to like it either. So be sure and thank a coal roller for bringing attention to this matter, and getting us where we are today.
I am glad I have a LB7 and am exempt from all the emissions equipment, but honestly, I don't have much of a problem with it. I'd love to see high-flow DPFs and DOCs come down to gas cat prices. Or exist at all, lol. There's nothing wrong with being clean while going fast. But there needs to be a demand before the parts show up.
And like most, I was mad at EFILive for doing this, but now that I think about it, they are handling it very well. They gave us plenty of warning, which is appreciated, and if you read between the lines, this might not be quite as bad as it sounds at first. But to continue to do deletes, we the users are probably going to have to do some convoluted steps, and EFI will have a plausible defense, saying we are manipulating/hacking their software, etc. This protects them, since the EPA no longer seems to care about warning notices or signed waivers. I hate that this is the case, but this is the EPA's fault, not EFI's. I'd rather have a less capable EFI than none at all.
And yes, this has been coming for years. While the YouTube smoke videos and coal rollers don't help anything, this would have happened anyway. The EPA & CARB have been tightening up enforcement of on and off road diesels (pumps, tractors, etc.) for over a decade, especially in CA where my parents farm. We will adapt. I don't think we have seen the end of diesel performance on new trucks. Just a setback to overcome.

Maybe it's been answered and I missed it but other then the obvious pollution is bad why the change? What happened ? The hammer came down on H&S even tho your out of the USA. Do you feel you are next?

The emissions equipment is a joke..........
I can take my 2007 LBZ in and tuned the way it is will pass with flying colors, no EGR/NO CAT !!!
Local buddy has a 100% stock truck, EGR enabled/working and CAT and full factory exhaust installed............flunked twice now !!!!
Go Figure, a high mileage ( 115K ) truck with all the factory emissions equipment can't pass..........so he blocks the EGR and get's a 4" down pipe back exhaust and passed with flying colors !
What's that tell me.........these systems are junk, some lobbyist got the Congress to agree to make these parts standard equipment and they don't do much IMHO.
:roflmao:

What year did EGRs come out 03? Has EFI said that they are continue to let us have control over the EGR in the pre LMMs? There last press release that I saw was kind of broad.
As I read it no, the EGR is part of the 'pullback' with DPF-SCR. I hope I read it wrong.
A functioning EGR isn't near the impact a DPF is though. Wonder if a FS would work in conjunction with EFI.

BINGO!
The fact that a diesel that had emissions equipment which was removed can be smogged and still pass says something about the 'effectiveness' of the emissions equipment on them....
But comparing catalytic converters on a gasser to a DPF isn't a valid comparison. The converters actually do have a benefit. They actually do reduce 'harmful' gasses, and while they can go bad, they rarely plug, and they don't limit what kind of fuel you can run (other than leaded, which you can't get from a pump anyway). The DPFs can and DO clog (and to make matters worse, if you have a TDI Jetta with a DPF, it WILL have to be REPLACED somewhere north of 100k to the tune of about $3500 - about 20% of what the car cost!!). The manufacturers say Biodiesel will cause problems, although I've read some info that seems to indicate Biodiesel is actually good for a DPF. If you happen to go somewhere that doesn't have ULSD (Say a road trip to Mexico or driving to Alaska - Does Canada have ULSD?) and you have a DPF, your totally screwed. And all for a 'perceived' benefit. EGR is another one... How much they really do on a gasser is up for debate... my car (17 year old) passed the sniffer with flying colors with the EGR disabled, but on a gasser, I don't think it has a serious negative. Diesels are another story.... at just under 40k, the two EGR ports on my LLY were about 40% and 70% restricted. Tell me how that particulate matter getting sucked back into the motor is good for it? Might as well not run an air filter...
The bottom line is the EPA is a freaking joke. I can see doing things up to a point to avoid pollution, but they've gone screaming past that point and taken a flying leap off the cliff that we call sanity. They call 'things' like the prius clean.... but they have caused more pollution to the environment before they even get driven on the road than a Hummer would in its fist 50k on the street.
I doubt that... if that were the case, then either both would have failed, or the 'stock' one would have failed both stock and with the emissions junk removed.
Along with the permissible (allowable) acceptable parameters. I recall years ago when having a gas'er tested ,they sampled everything,it would show up ZERO hydrocarbons or carbon monoxide ( I don't recall which) which impossible since it's burning gasoline running on rollers!

tony your LBZ might pass CT's absurdly easy particulate matter tests (come on, they allow 20% opacity, thats like 3x as bad as all the smokey casino busses we see all over I95), but it would fail miserably at a gov't level NOx test.
Come on, if GM could keep particulate and NOx in check while making 450hp or whatever your LBZ makes, dont you think they would have done it? I know you're a smart guy, but GM Powertrain also has some smart guys working there......
and BTW Tony. Something must be wrong with your buddys truck, or you arent telling us the whole story.........(like maybe your buddys truck was throwing EGR codes, but you conveniently left that part of the story out to make emissions tests look stupid????)........CT measures opacity and codes. Unless you have a sock shoved into the intake tube, there is no way in HELL a stock duramax with cat/egr/etc in place is going to produce 20% OPACITY. NONE.

The only places where diesel "emissions tests" arent a complete 110% joke are some of the super smoggy areas in california. Otherwise, everywhere else, diesel emissions has no real standards or anything. CT allows up to 20% opacity CONSTANT while driving down the road at a steady speed. Do you guys have any idea how much smoke "20% opacity" actually is??? Its a TON!!! They might as well not even test diesel opacity. Even a 30 year old detroit diesel 2 stroke isnt going to produce 20% opacity.
I'm saying the quality of testing performed. My friend took his Dodge two years ago before our mandatory 'dyno testing', and the shop that did the testing placed the sniffer on a shop bench 5 feet away from the exhaust.
But really it is a JOKE but a mere way to ROB money for NOTHING. Like I said their parameters set on their equipment that they allow are off the clock high so why bother to attempt to govern the air? It was a joke back in the 80's in CT when the program started and still is. Like I said a Nissan was put on the rollers for the test back then and the Nox I believe came up ZERO. You pass. How can that be? IMO it's worthless but a way to suck more money from you with the premise of clean air. But as you stated you cannot create enough pollutant to signal a fail. Worthless/ Junk
