I believe I saw different part numbers in the manual for this, but didn't realize the pipes might actually have been different...I'll take a second look to see if I come up with anything useful for you. It's definitely a neat pipe to see.
EDIT: Found what I was looking for. It's unfortunately not related. The other item was an alternate model that was for some of the ambulance models, which featured the exhaust being supported by a bracket near the roof height instead of at the fender. Not much else different.
