Cobra Technology and Lifestyle dual-mode exhaust – Click above to watch video after the jump

German tuner Cobra Technology and Lifestyle has developed a range of aesthetic and performance parts for the Nissan 370Z coupe and roadster. One of them is an exhaust with a remote-controlled butterfly valve that allows the driver to control how loud it bellows. Delivering the same kind of effect you'd get by revving an Aston above 4,500 rpm, you can buy 120-mm pipes with a flap that ranges from "discrete sportiness to pure racing sound."

You can check it the sound range in the video after the jump. Even with the flaps open it doesn't seem bad at all, but it might still come in handy for those hamlets where any kind of loud noise is a no-no.

The COBRA N+ Sports Kit for the Nissan 370Z Roadster

Exclusive accessories for the Nissan 370Z Roadster: Cobra Technology & Lifestyle (Alleestrasse 15-19, D-33818 Leopoldshöhe, Telefon +49 / (0) 52 02 / 99 92 60, Telefax +49 / (0) 52 02 / 99 92 50, Internet www.cobra-sor.com ) now introduces the COBRA N+ sports kit which offers exclusive options for upgrading the new open two-seater. All COBRA N+ options are also available for the 370Z coupe.

The COBRA N+ designers developed sportily styled carbon-fiber-look body components for the Japanese sports car: The COBRA N+ front spoiler precisely fits the opening of the air inlet of the production front apron, and lends the two 370Z models a more striking face.

Its aerodynamic counterpart in the rear is the COBRA N+ diffuser insert for the production apron. It was custom developed and features a centrally located reflector as well as custom cutouts for the two large tailpipes of the COBRA N+ sport exhaust system.

The standard rear apron is upgraded visually with the COBRA N+ rear diffuser. The aerodynamic component features a centrally mounted reflector and custom-tailored cutouts on either side for the large tailpipes of the COBRA N+ sport exhaust system.

The COBRA N+ 370Z body program also features carbon-fiber-look covers for the outside rearview mirrors.

For even more agile handling of the open Nissan sportscar the COBRA N+ engineers have developed a custom-tailored 19-inch tire/wheel combination which can be rounded off with sporty yet comfortably tuned lowering springs and sport suspensions. To reduce unsprung weight as much as possible the product range also contains the extremely lightweight COBRA N+ CN22 wheels with six double spokes. In sizes 9Jx19 with size 255/40 ZR 19 high-performance tires in front and 10Jx19 in back with size 285/35 ZR 19 tires they make perfect use of the available space beneath the wheel arches. At the same time these wheels and tires widen the vehicle's track, further increasing maximum possible cornering speeds.

Customers can also choose between COBRA N+ sport springs for a ride-height lowering of the roadster by some 30 millimeters and two height-adjustable COBRA N+ coil-over sport suspensions. The suspensions are made from stainless steel and come with either adjustable rebound or with adjustable bound and rebound. Both versions lower the ride height of coupe and roadster by between 20 and 40 millimeters on front and rear axle.

Sporty sound, optimized power yield, an even more striking rear appearance and top-notch quality are the hallmarks of the two COBRA N+ stainless-steel sport rear mufflers. The conventional COBRA N+ sports exhaust features one 115 x 90 mm tailpipe of either side.

Alternatively available is a version with an electronically controlled flap and two round 120-mm tailpipes. It allows selecting an exhaust note for the V6 engine ranging from discrete sportiness to pure racing sound at the push of the button on the radio remote.

The cockpit of the two-seater car can be upgraded with special carbon-fiber-look scuff plates with integrated Z logo.

A 2-year warranty with unlimited miles documents the high quality of COBRA N+ components and parts.

      The 2000 Nissan Maxima had an internal variable backpressure muffler.
      • 5 Years Ago
      I thought most sports cars came with this standard? my hatch has this kinda setup for god's sakes.
        • 5 Years Ago
        Why aren't these on every sports car? I've always had the fantasy of pulling a cord and opening up the straight pipe on my 10 second mustang to intimidate the guy I just pulled up next to at a light.

        and from a sales perspective, they are cheap and provide an awesome wow factor.

        @exboy99 - TT's lighter too!
        • 5 Years Ago
        You have a R32?
        • 5 Years Ago
        Ya he's got an R32. Almost everyone leaves them in the open position cause that unique VR6 sounds so good. I almost bought the Audi TT with the same motor.... It's virtually the same car under neath it all but that TT only comes with the automatic trans.

        Who knew exhaust flaps would be news. Let's talk downpipes next.
        • 5 Years Ago
        Its a sweet system and I hope it makes it into more cars although I do love the 370z/G37.
        • 5 Years Ago
        You may think this sounds cool, but it's really useless. You'll always leave it open. My RS4 opens exhaust chambers when you hit the sport button but I pulled the vacuum lines on the mufflers so they always stay open. It's still not loud enough!
        • 5 Years Ago
        This was standard equipment on the 2006 Corvette Z06, wasn't it?
        • 5 Years Ago
        @trustedcarsalesman - that's my point :). Super easy to implement, give the car a distinctly different character before wherever the cut off is set, lots of fun actually.

      This rates high on the wank value detector

      These kinds of gadgets always remind me of this video:


      WHOO WHOO!
      • 5 Years Ago
      so it has electronic cutouts... and I'm sure they cost a bit more than the same thing from summit.


      or if you have dual exhaust:


      They've only had these for... oh... EVER. And IIRC they have something like this on the corvette where it bypasses the baffling in the muffler at WOT.

      Home Association Approved (R)!

      That's pretty nice. A lot of high end sports cars have this from the factory or as an option. The difference is they're usually ECU controlled to close and open depending on the load range to actually give the greatest gain in power.

      If you've ever chased a 599GTB on the street or on the track you can see the flaps in action from behind while it's driving.
        • 5 Years Ago
        Working next to the largest Ferrari garage in my region has made me hate ECU controlled exhausts.

        The F430 or F458 or 599s sound silent one second, bark the next, silent again.

        The F360 on the other hand just sounds like pure bliss all through the rev range.

        You say an R32 can leave the option to always be loud? Hmmm, that might just have to be my next car!

        My '04 Audi S4 had butterfly valves on it that were controlled by vacuum pressure. The pressure would build enough at a certain RPM (around 4000 I think) and open up the valves. A common thing among the S4 crowd was to zip-tie the butterfly valves so that they are always open.

      What’s the point of a remote? Make a button inside near or on the dash, and save the in of replacing the battery in the remote and the remote itself when it gets lost, which will happen.
      • 5 Years Ago
      As good as that sounds, it'll never touch the sound of an L28 inline 6 from the old Datsun Z's. Properly tuned, the sound from the engine bay AND exhaust is music to my ears.
      • 5 Years Ago
      I must have missed the part where it explained that this is the equivalent of going to straight pipes. I think that this is more of a back pressure valve and not a complete bypass of the exhaust system and emission control devices. BMW has one that opens and closes based on rpm. A lot of the owners have modded it to stay open all the time. This option on the 370 is a lot easier than the modded way
      • 5 Years Ago
      pretty cool.
      • 5 Years Ago
      Wow, RICE straight from the factory... Didn't see that coming from Nissan. Why not just have some guy from Youtube that makes car noises with his mouth sit next to you with his head out the window?
