Stacks or back exhaust?
Hello everyone,
I've got a friend who runs dual stacks in his 94 F-250. We had a discussion regarding exhaust systems. He favors the stacks, saying it cools EGT by allowing a shorter distance for exhaust to travel. Although I'm not entirely fond of stacks, anyone have any ideas as to whether stacks make a difference? I know the diameter has a lot to do with it, but I'm scratching my head. Is there a performance increase with stacks versus normal back piping?

Stacks make ZERO difference in EGTs. After all there is only a 3" outlet at the back of the turbo, THAT is the limiting factor
Anything more than a 4" single exult is for looks and sound. It make ZERO performance gains

Dual exit pipes on any vehicle that, by definition, has single exhaust looks.... compensating. A SINGLE stack, done tastefully, can look right, but the real questions you gotta ask yourself are whether you want a hole in your bed, and whether you want the outlet that close to the cab and its occupants.

Well, I'm okay with exhaust being that close to my occupants, however I don't like the fact that I'd have to remove a small amount of space in my bed for a stack. I use my truck for hauling heavy supplies, and I figure I'll use the space under the cab and bed that was given to me...

Dude at our local farmers market has a stack setup I like. F-SD C&C with a frame set for a 9-foot bed (the C&Cs have those longer frames), put an 8-foot pickup bed on it, and has a tool box and a stack in the space in between. (Personally, I'd put a fuel tank in there if it were me, but....) Actually a pretty clean looking setup.

It has to be the right stacks on the right truck for it to not look tacky. Very fine line between "That's a sharp truck" and "Man, that guy is trying too hard"

Stacks provide no performance gains over "normal" exhaust routing, IMHO. Stacks serve a purpose and I have no problems with the folks that run them. I keep a camper shell on my truck bed 99.99% of the time, so stacks are not an option for me.
If you're going to add stacks, do it because you want them. They won't add any performance value to your setup. On a side note, my local truck club has sponsored some "Dyno Day" events. The dynamometer shop personnel are NOT fans of trucks with stacks because they usually aren't setup to run a "stacked" truck on the chassis dyno. The shop is smoked out before the dyno run ends.
