Stacks on diesel trucks?

Here's what I've learned from this thread:

You are going to put a stack through the bed of your truck because you want to put a stack through the bed of your truck. That's fine, because it will make you happy. It just wouldn't be my choice.

If it makes you feel better I would have the stacks too, but i also had airhorns, train horns and every piece of chrome and chicken light I could find so my taste maybe different than a normal person.

I say do whatever the hell you want. The consensus of GRM-types is going to be that you're compensating for something, but then most of the guys driving trucks with stacks think Miatas are for girls/Corky Romano and the difference between a porcupine and an E30 is that the "prick is on the inside".

Wow. Just wow.

I never expected such negativity (and so much misinformation) on diesels from this forum.

I like stacks, I'm not redneck, I'm not rice, and the whole EGT and air/fuel ratio discussion has me cracking up.

Stacks are nice if done well. They are an excellent way to reduce overall exhaust length, and allow for larger diameters without trying to bend around frames and axles.

I was being sarcastic about the noise issue as I doubt few of you complaining about diesels have stock exhausts, which many non car people would point at as being a sign of your small penis and find obnoxious.

Diesels work backwards.... they're always lean of peak EGT, so adding fuel makes the EGT go higher, not lower.

That said, smoking means there is too much fuel, or not enough time for the fuel to burn (combustion speed limit).

I recognize that with old mechanical pumps, some pre-boost smoking may happen. This is different to coal-train clouds of smoke AFTER the turbo is working, and inexcusable on modern computer-controlled engines.

Even in the DieselPowermag forums, there's people calling this rush to make tons of smoke "the new ricer wing". The problem is there are new laws under consideration which will wipe out Diesel production in America, if not limit it to uselessness. Ask UPS why it's switching to LS3's for it's trucks, and why Ford went ecoboost and not small diesel.

Wipe out diesels for private use or all diesels? because that's about as practical as outlawing the use of fossil fuels for power.

How is it that the rest of the world gets by just fine with diesels in all classes of vehicles?

this is the point I was trying to make.

Diesel smoke is the new flat black.

Strange that they would want to ban diesels, I was under the impression that europe had pretty much embraced the performance diesel thing for their cars.

I also have been told that diesels were potentially cleaner than gasoline engines because the carbon particulate just ends up on the ground instead of the air.

As for the sarcasm thing, it doesn't work well in text, that's why we have smileys.

Most non-car idiots out there think that -anything- that isn't a minivan or a hybrid is compensating for something.

Because they've had them longer than we have in all classes. Aside from a few Euro models and a couple of others there haven't been too many diesels in anything other that larger trucks and commercial stuff.

Plus, black smoke = dirty to the unwashed hordes. First thing most people think of when they hear diesel is the out of tune dump truck smoking like crazy or the previously mentioned d bags.

It's going away, but there are still enough aholes to keep small diesels out of America. It doesn't help that the automakers would rather you buy a fullsize than buy a diesel midsize, or an HD 3/4 and up over a 1/2 ton with a diesel.

as always... a few vocal idiots have to ruin it for the rest of us

Do you have a citation for that?

The other problem is that the only diesels you "see" are the smoky ones that people bitch about. You could be driving directly behind a new Cummins and neither smell nor hear the diesel. Heck, one can drive right up to you in a parking lot and you can hardly tell its diesel.

So people don't recognize cleaner, newer diesels because they don't even notice them. But they saw a 77 Mercedes the other day just smoking like crazy at a green light. It must be bad.

What I've learned from this thread:

There are a lot of misconceptions about diesels, with diesels, like most things, the few ruin it for the many, and we don't all like the same things.

I don't like stacks. I don't own your truck, though. Hell, I do like semi wheels on 2500/3500 diesel trucks, and I'm sure some people here would call that diesel rice as well.

Do what you like, but please don't make it smoke just to smoke. I know some of my cars have been loud and smelled bad, but I knew that I'd done what I could to minimize that - I still felt like a jerk in traffic though.

I should put stacks on my diesel Mercedes.

Do whatever makes you happy and berkeley people's opinions.

I do need a better horn on my truck... since the one supplied by Dodge is... whimpy at best... and I would like to let random drivers know that cutting in front of a 6000 lb vehicle moving at 50 mph wasn't the smartest thing to do...

If you don't want other peoples opinions, why post about it on an internet forum?

Sorry that just looks ultra-redneck. If you want something different that looks cool I'll second the pre-axle side exit.

I was at a light in my Miata the other day right next to a huge lifted Dodge diesel. The side-exit exhaust was pointed about the level of my head. I knew what he was going to do right away. Sure enough, when the light turned green he shot off leaving me in a cloud of black smoke. I was hoping he would get pulled over for going 50+ in a 35 but no such luck.

If he had stacks he wouldn't have been able to shoot black smoke right at my head so I support the use of stacks on diesel pickups.

Annoyingly, I don't have one off hand. I think I read half of it in a Train industry magazine, and the other part on a forum message board. The new Diesel regs are supposed to be part of a new government mandate from California (LEV III). We all know that if California's CARB board sneezes, the rest of the country catches a cold.

DrBoost wrote: Ok, I have to agree about stacks. I do have one question. Why is it most super fast trucks have them? I suspect the only way to pass a 6" or 8" exhaust is through the bed, rather than over an axle. Or is it because they wanna be a big rig?

The Haisley trucks run them all out of the hood these days.......Anyone familiar with diesel magazines should know that name.

And for the record, stacks are pointless, as well as all the unburnt fuel being thown around. I can live with the stacks, but when you get behind a truck smoking like a steam locomotive, and your windshield is actually covered in the oily black E36 M3, thats stupid.....just a sign of a poorly tuned truck driven by a tool.

To me it is country rice or as most call it diesel rice. But function > form so do as you wish. I laugh at the black smoke because A. It means you're going slower than you could be, and B. it is wasting $4 plus diesel.

Stacks generally aren't "muffled", even at that point, I don't mind the sound of diesel's, heck, my farm tractors and combine are louder than most stacked diesel trucks.....

Other funny thing I noticed when I went around for truck/antique tractor pulls was the simple fact of the diesel truck class always full of cummins/duramax entries, yet 90% of them were trailered to events by Ford powerstroke trucks....
