The new Chevrolet Corvette has a trick exhaust system that muffles the exhaust note when the electronically controlled valve flaps inside it are closed, and let's the V8 roar when they're open. The system works its mysterious magic depending on the drive mode and the engine's rpm. Here, Patrick Herrmann, Technical Manager of Chevrolet Europe, attempts to show us what's actually going on in the Stingray's exhaust system to give it its dynamic sound.

The informational video does a pretty good job of explaining the switchable exhaust system and compares it to a similar aftermarket exhaust system for Harley-Davidson motorcycles made by Dr. Jekill & Mr. Hyde. We know, the comparison seems kind of random, but we enjoy hearing the Harley, too. Watch the video below and learn something new today.

      As long as there's a fuse to pull to make it max exhaust all the time.

        Yeah!!! Agreed. Who is going to buy a 'Vette for subdued sounds? Ridiculous.

      Whoever decided to overlay the crappy r&r music over the exhaust sounds in the first part of this video should have their balls stomped on. Figuratively speaking of course.

      The most important find from this video... People -can- drive over 100mph and not die.* *void if the car was set to KPH on the speedo.

        I disagree. I think they look great.

        A donkey cart doesn't have an aluminum-block engine. It uses a donkey to propel it. Donkeys don't sound like combustion engines. Neigh. Hyperbole fail

      It's funny when men measure the awesomeness of their car by how loud the engine roars.

        Well I measure awesomeness by how well someone can read and article and watch a 4 minute video. You sir score low due to your clear lack of understanding that the Corvette could be obnoxiously loud, but was programmed and engineered to be quiet enough to not disturb you while you're enjoying an episode of Dora the Explorer.

        Yes because everyone knows a nice exhaust note doesn't increase the overall experience while driving a sports car....

          LG is already testing a prototype set of long tube headers for the C7, and just posted a dyno run (with just the headers and no tune) the other day.

          Headers are already being tested. This video also shows the npp differences. http://youtu.be/5rIrPdQu5uU

      How about owners just rip the over-engineered pile of crap off the car, and put on an aftermarket exhaust that sounds good all the time?

        Because it will drone like a mofo the rest of the time youre NOT going WOT. Ask me how I know. I wish they made an affordable dual mode exhaust for my G8.

          So now it only drones when you make it sound like you're at trombone practice. Yay.

        Look at the licence plates, they are in Europe.

        So you were the one complaining about Miss USA too? We should outlaw foreign brands completely then, since Germans shouldn't be allowed to own or talk about Corvettes.

        Only jingo and misogyny? I'm surprised you didn't narrow it down further with racism, zionism and agism, to "White, Christian, old, American men".

      i am so tired of this branding of technology! Switchblade, HEMI, SkyActiv, Blutec.... Just sell the bloody car and not the frills!

        @Bobby_Sards
        It's just switchable, meaning the exhaust valves can be switched between two modes. No obnoxious branding here.

        So basically you don't know anything about cars or automotive technology.

      My Audi S5 has this ability - if it's in "Comfort Mode" it mutes the exhaust system but if you switch the system into "Dynamic Mode" then you can wake up the neighbourhood. This is not really new tech, I know quite a few of the Audi's have had this for a couple of years now.

        GM had this in the 70s on the GTO. It was called the humbler.

        The c6 vette also had this. Its just a new way in which they're utilizing it.

      Why can't they put a nicer grill in the front? The rectangle just looks awkward on what is a very swoopy exciting design.
