Ditched the stock setup and got a custom solution. 3" with a resonator and muffler. Not too loud but a bit of nice sound under load. Smokes a little on start up and when you first take off.
I don't even know where to begin with this. But I'll try: VW dieselgate.
EDIT: It occurs to me that as a gasoline guy you may not be aware that the pictures posted by MNT250 demonstrate the removal of federally mandated emissions equipment. In this case the Selective Catalytic Reduction (SCR) and Diesel Particulate Filter (DPF).
Ahh, definitely a reportable incidence then.
Right, I don't know what a diesel exhaust is supposed to look like so having pictures didn't clue me in at all.
At least it's discreetly posted in a safe and secure location here on the internet. LOL
Some people hide from the government by unplugging their OnStar module. Others hide by posting pictures on the internet. Funny.
Enough from the peanut gallery. Very comedic. Thanks guys, very constructive. A shame about the warranty, you mean I won't have to take my truck in after 2000 miles for a plugged DPF? And they won't scratch my fender up while fixing it under 'warranty'? That's a shame. Guess i'll have to do my own repairs from now on. GM has come a long way. A few months ago they couldn't even seem to manage shipping a vehicle in a timely manner now they are crawling the internet and cross referencing data to void warranties? LOL!!!
It's really too bad for diesel in general what volkswagen did. Now enthusiasts attack each other, spout off about warranty concerns, EPA fines and worse can't genuinely talk about anything. It's sad. Do not see this going on on the gasoline side, on motorcycle forums or anywhere else for removing a cat. It's just unreal to me the attitude.
I really wish this thread could stay on topic about his mods rather than condescending harassment from those on a pedestal. I'd like to discuss his mileage change, if they dyno'd it, how the tune came out, if it's DSP4/5 or just a single tune, etc. There's a lot to be discussed and to learn about this new setup.
Wow, a lot of useless whining here. If you are all concerned so much about the EPA and the environment why arent you all driving a nissan leaf. You dont hear this stupidity on the big duramax forums about the trucks that spew out black smoke running down the 1/4 mile in 10 seconds not being EPA friendly...
Awesome mod, lets hear about how it works, driving impressions, tuning, milage, dyno numbers, etc...
Why does everyone jump on anyone that changes out their exhaust on here? If you like it let him know, if you don't like it feel free to start your own thread about how much you disagree with tampering with emissions equipment. The constant beatings over stupid thing you don't like is what destroys forums for most of us.
agree. its just an exhaust the OP likes and whether legal or not for him to run is not our concern. It gives others an opportunity if this is something they may want. I personally don't feel the sound is better or worse really so just a lot of money I would not spend.
It was all put together relatively cheap, it was not a purchased system by a vendor. Obviously due to the nature of it people going this route will need to have the know how to do it themselves. I did the programming for the ECM, no issues or check engine light in 500 miles so far. No drone or annoying sound, just a little nicer tone under load.
I was running the calibrated power/duramax tuner tune prior to this and I do miss the raw power but I was doing a regen every less than 200 miles. Not good for the life of the truck, not good for the environment, not good for my MPG. During regen in city driving when it was warm out I would see trans temps of 220 F.. Not good. Mileage i'm seeing about a 5 mpg gain on average. Since then I have run a full tank of biodiesel B99 and the truck seems happy with it. Runs smooth and quiet. Performance does seem better than what I remember stock being, but it has been awhile since I ran a stock tune and I haven't dynoed it so I don't know for certain what the numbers are like now.
I only wanted to share so other owners thinking about it know what to expect, i'm not flaunting it, I don't think laws don't apply to me and I do care about the environment. I assume anyone considering does know the risks involved, i'm only sharing my personal experience. It's a touchy subject (seemingly more so to people that don't actually drive diesels or a duramax twin at all somehow). I believe diesel vehicles make up something like .05% of the cars on the road in America? So why the such harsh over regulation? Even in my vehicles current state it will be much cleaner than the old diesels still on the road operating unregulated. Especially when running B99. Study after study shows larger particulate matter poses less harm than ultrafine particles they are replaced with that stay aerosolized and in our air for weeks or months. I have also read the result of NOX reducing urea reactions is more carcinogenic.. It's not so black and white. Of course you can just blindly start spouting off about dieselgate and this and that but if you aren't happy with it, go buy an electric car, stop picking on me, stop picking on diesels. All vehicles even those pose environmental harm to the environment it's just some look cleaner on the surface than others.
Any other vids yet? Interior cruise/acceleration, exterior cruise/acceleration, etc. Very curious to know what this set up sounds like in driving situations.
Man I wish WA was just a little closer to VA I'd love to check this out in person. I have been looking at doing this in my truck but am holding off till at least 10k miles for research purposes.
