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)
