The De-Type in Canberra had to go through rego with the exit pipes pointing in .... The exit pipes are made to rotate ... (there is a slight blister in the paint under the passengers side...
)
The De-Type kit is also lower, wider and longer than most, so maybe there are some different circumstances...
I contacted the engineer last week (arranging for what I need to look for when ordering a kit) - his comment was that the ACT authorities like to try and get you on the road, rather than be real pains in the .... so he has a good working relationship with them - as long as it meets certain regs, there is no problem. But you must get them locked to certain conditions as early in the build as possible (then go for it).
The De-Type in question can be seen here -->
