Hell back in the 60's my grandpa used to run stacks out of his pick ups. I'm going to be putting a stack in my 4x4 f250 gasser I'm going to run 3in for the time being then I'm going to slide a 4in chrome stack over it.

Im looking to get 6in aussie style when I get the money and I couldnt agree more with the last part "Like they say I didn't build my truck for you to be happy"

The old Dodge Lil Red Express trucks from 1978 and 79 came stock with stacks. So even if it is stupid looking, it makes more sense than stacks on a diesel. If you will, you only get one down pipe with a diesel, whether its an I6 Cummins or a V8 PowerStroke or Dirtymax. Either way on those you won't get an even amount of exhaust coming out. On a V8 gasser or old IDI it comes out in even amounts if your running true dual exhaust.
You want to run them along the outside along the gap between cab and bed or you want to run them inside the bed?
Here's how the Lil Red Express truck stacks were done Dodge Li'l Red Exhaust and Steps scroll down a bit and you'll see from the front back.
I'm on the bench with this idea. I've thought about it but I don't know. If your running with mufflers you'll need to get either a new pair or get one more. Keep the cats. Just have to get new pipe and weld it in. Also if your running mufflers at least you'll be able to keep a conversation going on the phone or with the person next to you unlike a diesel where you can't hear jack crap.
You could run the exhaust side ways along the bed of the truck and have it dual side dump.

What is wrong with stacks on a gas '250?There is a guy around here that has stacks on a Ranger, looks good too.Not a diesel either.As was mentioned Dodge equiped that little red truck with stacks and it looks good too. It's his truck and he can "paint it any color he likes".

I'm not a fan of stacks either(on gas or diesel). In my opinion they look bad, are too close to the driver's head and waste valuable bed space. But like you said, your truck, and only your opinion matters 
. I would seriously consider the smaller pipe inside of a bigger pipe like was recommended. You need a certain amount of backpressure in order for it to run efficiently.
On a side note, do it right if you are going to do it. There is a ranger here with 5-6" stacks, a dodge ram with road tractor stacks(about 6 feet above his cab) and an f250 with a single stack on his flatbed where a gooseneck ball would be.

Well you'll lose bed space if go through the bed. Either way you'll need about the same amount of exhaust pipe, might be a difference of a few inches at the very most, just measure twice cut once. Cheap wise, depend on what type of metal you want your exhaust to be. Stainless steel won't rust and if you live in the rust belt it'll be beneficial but more expensive. If you want to save money you could use flex pipe, but be warned the stuff doesn't last more than a couple years.

My buddy is a huge diesel guy and though his daily driver is a 95 F350 with the 460 big block we put stacks on it! Hooker long tubes into three inch pipes then into 7" Pete stacks! The truck sounds AMAZING!!!!!!!!! what we did was have a local metal shop cut a stainless disk that fits inside the 7" stack about an inch which we welded in, the machine shop cut a perfect three inch hole in the disk where the exhaust pipe fit into that we welded the exhaust tubing through. Simply and strong..... And don't forgot to drill a small hole in the lowest part of the exhaust system so rain water and snow will drain out, sucks when you start a truck that rain water filled up the stacks and you get that gargle sound for twenty minutes......

Oh how I seriously hope you are being sarcastic. Straight piped gas trucks sound like crap. Very wrappy sounding and some even sound like it'll blow a gasket. Unless he is trying to tick off his neighbors, going straight pipe isn't a good idea. Especially in neighborhoods where they have a noise ordinance, around here you could get a $200 fine for "disturbing the peace" before 8am. Hard enough to tolerate Jakes at 2am from a Peterbilt.
