The outlet of an exhaust system must be rearwards of any passenger side entry door or opening window.
Exhaust systems must provide a minimum of 100 mm ground clearance.
The maximum exhaust noise for a 6 cylinder measured at 3200 rpm is 81 decibels.

So you can have it exiting kerbside pre 1988, but needs to be aft of opening rear window. Is that doable on a torrrie?

Non-opening passenger window maybe?

This is legal in SA due to vehicle age, but the cops assume it isn’t.

He's pretty picky Clay,
Pre-1988, 400mm away from an opening, 100mm off the ground, and with-in the outside of tyres.
Exhaust tip should be angled down at 15 degrees.
Nice chrome:

I put a 2.5 inch side pipe on mine for an event at Bathurst a couple of years ago.
As much as I love the sound, I took it off again as they aren't legal in NSW because it's not far enough from the door or the side windows that can open.
I did get both systems made so i can easily swap them for when I feel like being a hoon
