Outer Limits 4x4 Board

Own a 80 series cruiser and looking at choping the exhaust at the back of rear wheel.
1. cause the wheel hits when flexing.
2. the tail muffler catches on everything

Question.
What are the rules as far as where your exhaust can and cant exit.
I heard that it has to be so far from closest door or window.

Any info would be great.
Queensland especially.
Thanks Steve.

i was of the understanding that it had to exit behind the most rearward door opening door or window.

does that mean it can come out the side behind rear door?

Id say not, if you have the barn doors it would have to be out past those. If you have the tailgate style 80 series it might be a different story.

Tail pipe must exit no furthure foward than the last pivitod/sliding/roll down/roll up window

and must not exceed past the outer most dimensions of the vehicle
