Upright exhaust conversion on front-engine

I have a 1997 39' International front-engine dog-nosed bus. I was curious if it was possible to move the exhaust to an upright stack near the front cab. As it is now, the exhaust pipe runs all the way down to the very end of the bus.

I'm not sure why it was built this way (maybe to reduce clearance/help kids to not breath exhaust fumes?") but I was wondering if it was possible to make it upright like most semi-trucks have.

Are there disadvantages to this? Does it affect emissions in any way? I would like to have a little bit more working room under the bus as well as the potential to heavily modify the back-end (maybe cut a section off)

A short stack coming up on one (or both) sides would be very cool. I have seen it done on a skoolie before, just don't know where the pix might be. As long as there is a standard rain cap on top...why not?

It doesn't seem to safe to have the exhaust so close to the diesel fill??

Jake C also had his bus running a stack.

His build thread.

The state mandates where it is on the school busses(in ohio, it's either out the back or in front of the driver's rear tire).

I don't see a problem with running a stack. I'd prefer to see it run on the opposite side of the fuel tank. I'd also put some sort of a guard on it to keep someone from touching it and getting burnt. I don't think you'd need a rain cap with the distance it is from the engine, just drill a little hole at the bottom to let any water out.

after towing with a skoolie with the standard out the back exhaust.... a stack sure would keep that trailer cleaner.

Yeah, that is another huge reason I want to swap it out. I'd hate for that exhaust to infect my pop-up trailer.

I wonder how high one would need to go to avoid exhaust condensing on roof solar panels.
