I have been seeing more and more trucks with these big stacks sticking out of the bed, do these serve a purpose or are they just for looks?

 

YES, it feeds the EGO.................

 

......and looks stupid!

 

If you have a Cummins, it almost makes your truck sound like a dump truck.

If you have a Ford, a 7.3 or a 6.0 will just make a lot of black smoke if you tune it right.

If you have a GM, you can make a lot of black smoke with a tuner.

If you have stacks, you are showing people that you think your truck is all big and powerful, just like the big rig tractors.

It's true that some people open up the intake and the exhaust, removing all the restrictions from the factory, stacks do this too, but a regular straight pipe also works.

 

I think it is called "The Big Rig Syndrome'. I just have to laugh, must help them feel like a man.....

 

I personally think they are obnoxious. They do what everyone else described. I think they look rediculous and have always wondered why someone would want to cut holes in the bed of their trucks.

I stumbled on this vid on you tube.

This helps guys with small lower members compensate

 

I saw a Ford Ranger (yes I said Ranger) with a single 6" (or larger) stack.
What a stupid looking addition.

The truck had nearly black windows so I couldn't tell if anyone was inside the cab so I didn't take a picture.

After I was finished laughing, I had to ask (myself); why???

 

As if looking and driving like a dump truck isn't enough, eh?

And you have to have rain flappers:

I had a singly 5" Aussie style stack, position like this guys truck, I actually had a lot of people come up to me and say they usually hated stacks but thought mine looked good. Then I bought a slide in truck camper so out she came, put my stock exhaust back on but just modified the end to have a 4" pipe leading into a 5" tip, no noise anymore.
