I'm just going off what I've read - that all butterfly systems are illegal. Maybe it's only in some states. That said - if it were legal dB when fully-open, probably fine. I know some cars have these factory fitted - but obviously that's circumventing the issue.

A quick search picks up these threads discussing it. Mostly referring to Sydney, but yeah --

The last has an interesting comment - not sure how relevant in SA? I think EPA is national?

I'm not sure whether people are aware of this, but under part 19(1)(d) of the Protection of the Environment Operations (Noise Control) Regulation 2008 which commenced on 1 March 2008, it is illegal to have temporary noise reduction devices installed on vehicles. Part 19(2) provides 6 months grace, so this means that people can't be defected for noise control devices until 1 September. It is worth bearing in mind if you either have one of these exhausts fitted or are looking at fitting one in the future.

I thought it was to do with modifying the exhaust flow on-the-fly changes the emissions of the car? I could be off base though :whistling:

Interesting links there Jenna. And while noteworthy, I think an ECV is the LAST thing that most of us would get defected for :) .... but it would be interesting to see if you would or would not get through Regency with one fitted.

The apexi one is just a flange with butterfly valve in it yes? With a cable you run into the cabin? If so, as long as you hide the switch good enough, how would regency ever know it was there? Wouldn't it just look like any other flange in your exhaust?

the bracket, and cable running off it going to the cabin somewhere would be a give away. As someone wise once said, they are assh*les, not idiots. From memory they even made someone weld in them silencer tips that you can remove to make it legal.

Considered one of those Dynomax VT mufflers? Unsure how well they work, would at least quieten it right down on idle.
