I could not get the video to work correctly. You should post it on youtube.

2900 euros? Did I read that right on your website? Looks like you all also have a Carbon intake like the CSL intake too.

Do you have more pictures? possibly of a cutaway of the inside? I'm guessing that when opened it switches to an unmuffled pipe, but when closed what is the sound like.

I have a set on my car currently right after the (catless) headers. There especially its fregin loud. Loud enough that whenever I open them and floor it the car loses communication with the DSC system

I was going to move them farther back to the rear, but depending on how this system is setup I might go for it instead.

The price 2900,- Euro VAT included. For you guys it is 2400,- Euro = about $3000,-

Shipping is not expensive because it is a small system.

And yes it is loud as hell if valves are opened and if they are closed it sounds nearly like stock but a bit deeper. Like a Eisenman or Remus standard muffler.

It is a mp4 Video you need this codec http://www.netzwelt.de/software-choo...eg4-codec.html to make it work.

We Do have a Racing Carbon Box CSL like which we are using for Nordschleife VLN Z4m Coupe's. It sounds sick and gives you a lot of hp with aditional mods.

With a Standalone ECU and Highlow Cats it made about 410bhp.

But you can use it just without any adittional mods it makes about 10 more bhp and the sound makes your skin crawl.

if you can live with the sound, i think these are the way to go. retain stock exhaust, huge gains and have fun setting off alarms. i heard this on my friend's audi s6 and i swear it sounded like a bomb exploded, lol.

Have any videos of the system with the valves closed? That is of more interest then the sound of them open.

It sounds pretty much like stock. So everybody knows how the car sounds stock. It is a video from a customer he did not make a video with closed valves. But you can watch our videos at our hompage to get a clue.

I cannot get these rapid share videos to work. BTW, you can go to youtube for the E92 M3 with this company's exhaust. You can see how the flap system works and changes the sound.

Okay- got it now. I like the idea of being able to tone down the sound when you want....Butttttttt the price would have to under 1500.00 USD for me to even consider it.

How much is the carbon intake?

You can choose tips. Tips can be round, oval, squared you get what ever you want. The titanium finish is only one option. I will post some pics installed later.

The Full carbon Fiber Airbox is $2269,-

For the exhaust price.

$1500,- must be a joke for handmade quality with elektronic vlave system.

The Eisenmann muffler does cost $2500,- without valves and made of poorer quality.
