There are a lot of people running stacks in their truck. There are a few reasons to cutting a hole in the bed and running the exhaust pipe upwards.

If you are into competition, there are rules that the exhaust must exit upwards from a vehicle. This is to reduce the chance of someone getting hit with shrapnel from a turbocharger that grenades at full boost or it could be to reduce the likeliness of smoking out a starting light.

For others, a stack is a statement piece. These individuals love the way a stack looks and aren’t afraid to experiment with a different and unique look. Over the years, we have seen a ton of different stacks; everything from a single 4” tube to 55 gallon drums. Heck, if you search the internet you can find people selling 36” stacks and videos of just some crazy looking setups.

In addition, there are others who run a stack for functionality. Whether that is because their truck has too many things under the truck and an exhaust pipe won’t fit, or they have altered their suspension and now there is an air bag or something else in the way. Another reason for putting a stack on a truck is for smoke management. If the truck smokes a decent amount, putting a stack on the truck is a way of not smoking out everyone around you during rush hour.

We have, also, seen a few guys with stacks really high to blow the smoke up and hopefully over their trailers. This helps to keep not only their truck clean but most of their trailer.

Basically, there are a ton of reasons to run a stack. For most of us, we would never have thought that a light duty truck might come with a factory stack. Last year, SEMA News ran an image from KGP Photography showing a prototype F-350 with what appears to be a Ford stack in the truck. Check out the article from last year here.

Then April 24th, SEMA News ran another shot from KGP Photography showing another version of the exhaust stack. This time the “kit” looked much more production ready. This is extremely surprising to us. Anyone who has been under a newer truck knows, there isn’t much room under the truck to run a stack kit easy with the DPF and other emissions devices. In addition, the sound level inside of the cab on a truck with stacks is usually much higher than what is acceptable by the factory.

So, to see the continued development of a factory stack is pretty interesting. There is no word yet from Ford about whether this is some experiment that we will never see, or if this is a soon to be offered production piece. We will keep our eyes out for more info. But check out the recent photos!
