The Nissan 370Z definately sounds enthusiastic, in fact much more than the 350 it replaces. But when heard passing by at full note, it can be a little subdued. To change that and offer even more aural pleasure, German tuner Cobra Technology and Lifestyle has developed a remote-controlled butterfly valve that allows the owner to control how loud the car is, this product is a part of wide range of visual and performance parts for the 370Z.
The remote-controlled butterfly valve includes 120mm pipes with a flap that helps the Z sound from anything like a laidback cruiser to a all out race car. Check out the video by clicking here.
