For those who don't know what the bi-modal exhaust is:

The $2659.99AUD ($2,073.97USD) bi-modal exhaust system was developed by Melbourne-based company Lumen specifically for Kia Motors Australia. The system works by replacing the rear mufflers to a set of electronically-switchable pipes. There's a bypass valve open or close depending on the drive mode.

It's set up so that it operates in the three modes, at varying degrees of activation. So you can drive it in Eco and not have any noise, whereas in Sport you?ll have noise from start to finish.

Awesome. Wonder how much would it be shipped to the US. We are talking JUN B.L money right there.

I might depending if the price is lower, but I highly doubt the state of CA would approve something like this.

What is the third mode? RPM activated? And it is an option added to the Custom mode menu choices (I sure hope)?

I assume he meant the three main driving modes the car has. ECO, Comfort and Sport.

Sure, so how does it operate in Comfort then? There are usually three modes for these systems (On, Off and RPM activated). How they match those with the drive modes is important and could be smart or dumb. Custom is especially important.

The australien bi-modal exhaust is not the only one available worldwide. In Germany Kia also offers a bi-modal exhaust as an official option for the Stinger. Here it?s speed controlled. Valves open at 70km/h. You get a new button next to the steering wheel. With that button you can just close the valves in case you don?t want to get bothered on long trips. The exhaust system is made by Bastuck.

Yes, exactly. So it also doesn?t harm the warranty. I will get my Stinger with this exhaust system in 3-4 weeks.

You can actually buy the Bastuck system and have it shipped here too. It's just not as integrated as the bi-modal.

I voted, yes I want a bi modal exhaust system. Three modes would be nice. Open, closed and engine RPM (not car speed) activated. That system from Germany that's "speed" activated is not what I would like if I understand it correctly. I'm wondering if something got lost in translation and they meant to say engine speed?

Agree that rpm-activated makes sense, but road speed does not.

No you got it right. It?s car speed based. Has to do with the german regulations. It?s like that because that?s the only way to run it legally here and that exhaust system development was focussed on the german market. In Germany a car is not allowed to be louder as stock at low speeds. So Bastuck had to be sure that the valves cannot be opened < 70km/h. So if you don?t live in Germany you should really think twice if it makes any sense for you to buy/import this solution - esspecially if you consider the price.

I don't think a cutout's legal in the U.S. anywhere, is it?
Not sure, but the Lumen one or whichever one Kia is testing for broader use surely will be a properly integrated system that doesn't bypass any emissions equipment or cause undue sound issues. Like the ones already available from the factory on many other cars for many years, including the usual suspect German ones!

As long as it's after the cats, you could get refused inspection for unsafe exhaust exit (if it's before the rear wheels and the tech actually inspects it, but this varies by state and county) or a ticket for noise if a cop hears you. If it's before the cats then you'd be refused inspection for emissions modification (again, if the tech actually looks).
Cutouts are legal to buy and install.

Note that 70 km/h is only 40mph or so, which you get to pretty quick. Sure, it won't scream while revving in the parking lot, but I think that's ok.

I think for states that require a visual inspection it may be a problem, not really familiar with their laws, but on states that only requires an emissions inspection, it is not a problem.
