Even the Dodge Lil Red Express that came from the factory with stacks?

I agree with some of these other guys dont do it man! Looks good on most new body style diesels but not these old gassers!

 

Why?.....I thought stacks were on big rigs and dump trucks and stuff for a purpose like keeping dirty exhaust off of the trailers, pedestrians, and city driving, and they were soo big because of the massive engine? Also, big trucks have REAL deseil engines wich have differnt needs and requirments. So, unless someone plans on putting a 1,200LB+ REAL deseil engine in a truck instead of a "deseil" like a cummins, powerstroke, duramax or other random engine that are basiclly a gas engine without spark plugs......why? If you have a pick-up, or suv....keep it looking like one....not a big-rig wanna-be. And as for the 5" stacks, like i said, look up the specs of a REAL deseil engine, they are like 1,200LB turbocharged 4 cylinders, 400HP, 1,300 LBs of TQ, and they need the pipes. As for a little gas or deseil....even if it is a 7.3 or whatever...no need for it. And yes, some trucks do have small 2.5" stacks, but not for wanna-be looks. It is for deep water crossing, and when used with a snorkle as well as a waterproofed ignition and truck, they serve their purpose. So, i guess you can tell that in my opinion, i think "stacks" are not for pick-ups or suv's, even if they are a deseil.

 

I agree about the bed also, just like "stacks" have a purpose on REAL deseils like big rigs, beds have a purpose on pick-ups and that purpose does not include exhaust sticking through them......

 

I have seen some dents with flatbeds or service utility type beds with stacks that looked pretty dang sharp, however the stacks ran up the back side of the cab in front of the bed, not thru the bed. And they were dual rear wheel one tons. In fact I may do it to my 96 F350 Powestroke service truck at some point. They WILL NOT be 5,6 or 8" stacks though. More like 2 1/2" with some perforated heat shields (think '70's style side pipes mounted vertically}. That way they are proportionally correct and dont look like someone dropped a big chrome pipe and it stuck............

 

Umm ... WOW!! Thats a little on the uneducated side isn't it? Let me start by saying first off that the days of the "converted" gas to diesel engine in a passenger vehicle are long gone. Second, Powerstrokes and Duramax engines are much different than "gas engines without spark plugs." They are a true diesel engine. They may be "V8" in design but that is the choice of the manufacturer. As far as the 6bt and 4bt Cummins engine that are used in production vehicles, you may want to take a look at that design as well. For all purposes, it is a slightly smaller version of the same engines that is found in road trucks.
Last of all, you need to look up the specs of a "real" diesel engine yourself. Almost all road trucks are powered by an inline 6 diesel engine. Power outputs can range anywhere from 225hp to 600hp. They do have torque numbers over 1000 ft/lbs usually. You are right that stacks are "normally" put on trucks to clear suit and smoke from the line of sight of other motorist. However, you do need to do some research on what these production pickup trucks are doing these days. Ford, Dodge and Chevy. With the simple addition of a tuner, new turbo and a set of injectors, these trucks are pushing 400-800 rwhp. Yes, thats REAR WHEEL HORSEPOWER!! They are also laying down 600-1200 rwtq numbers. To me, thats not a "LITTLE" diesel like you stated. And YES... most of these pickups need 4-6 inch exhaust to get it done. All while still getting 17-25mpg!!! Do you want all that smoke in your face? Thats why they run stacks. Plus the NDHRA and NDPA require upward facing exhaust in case of turbo failure.

 

Stacks really turn my stomach

 

There needs to be an upper size limit too though. On another forum I'm on I've seen pics of trucks with about 12" dia. (yes 12 - not a type-o!) posted. They look worse than the 2.5" ones. Oh, and speaking of the 2.5" ones - the only time I've really seen those is on a trail type truck that gets used a lot and the exhaust is routed up to keep water out of it during stream/water crossings.

I'm not a huge fan of stacks (hardly ever see them here in So. Cal.) but I have seen some that look clean/good. I BRIEFLY thought about running a single, 5-6" stack on my '74 crew that is getting the cummins. Since I will have a chase rack on the bed though and tires will be sitting up there on it I don't need my exhaust heating up the tires...
Instead the current thought is a hood stack or quick exit behind the front, passenger wheel

 

I'm sure glad to hear that most of you dentsiders don't like stacks (I used to be a dentsider too) buy my group on the '99-'03 PSD forum seem to like the stacks....I think stacks look stupid sticking through a pick up truck bed regardless if its gas or diesel powered.

 

Chasetruck, go for the hoooooood stack! I've always thought there's no meaner look, wanted to run hood pipes on demo cars in the past, but never had the time to spend making them, when they were just going to be destroyed.

 

would a hood stack be legal? not that I'd go that route just wondering

 

go to youtube and type in "alaskaforby4" that guy has a 76 or 78 dont remeber f-250 with stacks in most of his video's

 

Like I said...JUST MY OPINION....pick-ups dont need stacks....if you really do get a peterbuilt

 

I like that alaskaforby4's truck except for the stick on scoops, the stacks look good and sound really great-think one video said its a 390.I'm gonna go stacks and trying to decide between flat black or army green-either way it'll be 2 tone with white on the middle of sides and on the roof with a Boss 429 or early hemi style scoop

 

Hmmm, 2 pages of opinions but not a single pic.

Do some searches on some popular car/truck sites (cardomain, supermotors) on the year(s) truck you want to see or google images and see what pops up.

With aesthetics; you can play with some simple photo editing programs to see how placement and scale work out. Taste is an individual thing, it's your truck and there's only one person you need to please. If you go this route post up a pic.
