Has anyone figured out how to bypass the emission sensors and the exhaust fluid?
I'm sure someone has somewhere. Nothing has been publicly released however due to the fact that it would be illegal for them to sell such a modification and it would be illegal to have on your car.

Legalities aside and the fact you wouldn't have to use DEF, what's the point or more succinctly, advantage? I know many who own TDI and the ONLY advantage they had was the lack of a DEF tank.

The only thing I can think of, is it would be louder, since you could remove the SCR, which acts as a muffling device (which is why there isn't an actual muffler, as it does a good enough job).

It would open alot more possibilities to increase power plus I want to get rid of the tank in my trunk. I have other plans for that space. Also I want to straight pipe my car. I know there isn't a muffler on it but the filters and **** got to go.

One advantage would be power increase. Diesels love to breath, opening up the exhaust can make a big difference. On my 91 Jetta, I went from a 1.5" to 2.5" pipe and my boost went from 9psi to 12psi and that is the only thing I did. It will also help lower EGT's.

Diesels are great but the biggest disadvantage is emissions, trying to keep it clean for the EPA really kills their potential.

That's actually true with gas/petrol vehicles as well, they all like to breathe. I have a LOT of experience with AMGs and have found that a nice exhaust (even Cat Back will sometimes do), intake and a TUNE will really open up the car to better performance and even fuel mileage. LOTS of guys in non-testing states will even take off the CATS (and put them back on upon sale of car). We often take off limiters (speed) and that's a nice perk from a tune.

To the OP, in lieu of removing the tank, why not just open up the exhaust with larger diameter pipes like big trucks do. The DEF will not affect what you do on the exhaust side of things as long as the exhaust gas sensors are still attached (which they can be easily).

Most vehicles with modifications have lower resale values, so I'd imagine so.
This is very true from my experience. Most "buyers" know that a modded car has been "run" and most likely run hard. I don't mind a few QTR Mile runs, but some of these guys run these cars hard and all the time.

Except for very few cases (where you can tell the owner isn't an idiot - or you know the owner, and know how they treat the car), this is pretty much assumed. I mean, my Cobalt is very far from stock. If I were to sell it, it'd have to be sold to someone that knows the history of the car, knows I take care of it, and while I drive it like I built it to drive, I don't go out of my way to abuse the car. But once again - the average person will see my ad for "2007 Cobalt LT - Supercharged" and just assume it's a piece of ****.

Another issue people have, is a matter of if the mods were installed correctly. Especially when it comes to a freshly-rebuilt engine, or something like that.

I've seen poorly done ECM tunes trash an engine, so I am with you there. Air/fuel ratios is a big one and a LOT of guys don't even dyno their tunes and see how the car is doing once heated UP etc.

Eleiminating the emissions system would yield only positive results. More power, less fuel consumption out of the gate, and the biggest positive to me is greatly increased reliability and not having to worry about driving habits to maintain emissions system.

Fleece tuning did a complete full delete on their CTD but it was for their own fun. They won't do it for others. A member here saw and road in said vehicle and said the results were nothing short of spectacular!

I would be willing to pay cash money in a heartbeat if there was someone reputable that would do it but sadly with such a limited release vehicle I don't ever see it happening. Also the recent vw thing is only going to hurt matters.

In the big rig world I know guys who first thing they do with a brand new truck is put 10+ grand into it right away to delete dpf, egr, and scr. It pays for itself quickly with the fuel economy gained and lack of downtime in the shop fixing the emissions system.

I'm all for emissions as long as it doesn't significantly reduce economy and reliability which the current only known method to meet epa regulations Reduces both.

For the life of me I can't understand how burning more fuel and requiring loads of chinese rare earth metals for the dpf's is the best idea for humankind. Not to mention the extra trucking, packaging, and energy to make DEF. I just don't get it. It has to come down to money for someone, somewhere like everything else.

I'd love to swap one of these into a '71 Benz I have if it could be made to work standalone without all the other impossible to swap crap.

More power, quieter and cleaner than an OM617 3.0 Turbo-diesel I have I might otherwise swap into it. Because the Mechanically fuel injected M130 2.8 that's in it is a thirsty beast that consumes mass quantities of 93 octane and puts up a noisy fuss if you put anything lesser in it.

I would love to be able to gut the exhaust and gain more reliability, power and efficiency.
Fortunately, sofar I have not had any DPF, DEF or sensor issues to date.

I am more on the side of clean emissions, but you make some good points there.

Im all about as clean as reasonably possible too, the way we currently do it just doesn't seem reasonable to me. I love diesels and the future bums me out a bit but you never know

Is this a joke comment? Havent you seen hundreds of post's about how unreliable your car is because of junk emmision equipment? Ive been to the shop twice in 25000 miles, my Duramax has 189000 miles and still no CEL's due to emission sensors because they are laying in my front yard. Fleece and Trifecta need to step up and have us sign a off road waiver to purchase a delete tune. I got $1500 on it as well.
