    O sure, you see them on some new trucks. But all the big fleets have gone to those grass burner types. What gives? Why the switch. I'm sure it's to reduce cost but then what was the purpose of a smoke stack to begin with. I haven't had a truck with a decent stack in over 2 years. Sucks that trucks are getting more ugly as time goes on. Hopefully we can do something before we are all driving one of those elon musk futuristic looking dildos lol

    It has nothing to do with the big fleets. It's the engine manufactures that put them under the truck.

    Engine manufacturers have nothing to do with how a truck is ordered by the customer. The easy answer is that a 2ft piece of pipe is cheaper than a couple of elbows and clamps and an 8ft piece of pipe. And with many people running some type of anti-idling equipment it’s not as big of deal to dump the exhaust out under the truck as it used to be.

    I miss seeing the "con trail" rolling off to the back and side on those 0 F mornings as you begin your day. Now you can't tell if maybe you're on fire or what.

    But really. how can a round 5 inch pipe pointing straight up, parked in a period of 4-8 inch rain be better off with that water sitting somewhere in the exhaust system?
     
    Brickwall, InTooDeep and OLDSKOOLERnWV Thank this.

    When the new trucks go for that def burn those stacks that point at the trailer or fuel island canopy can start a fire, having them under will only start that grease strip on the ground, lighting the truck up also and making a great you tube video.

    They use grass burner exhaust to reduce back pressure, thereby increasing fuel economy. ( In more ways than one)

    I personally miss seeing a nice set of stacks on an R600 Mack rolling some coal, unlike these tools with a Ford F350 with stacks in the bed.
