Varex Exhaust on an R33 GTS Skyline.
7" cannon Varex muffler with 4.5" tip and 2.5" catback on a non turbo R33 Skyline. For those that don't know the Varex muffler is designed so that when open it gives off the full, loud volume you'd expect from a cannon. When closed however, it is quieter than a stock Excel, I am not exaggerating. It is controlled by a remote control that I had on my keyring. Another thing to note is that the camera I used to film this is an $80 POS with the worlds worse microphone, it is also directly in front of the Exhaust pipe. This means the sound you hear is nothing like what it sounds like in real life. In real life the car had a nice, typical RB25 note, was a little drony at 100kph, but this was easily fixed by closing the muffler. The point? Loud cars are great, but not all the time. With this muffler you can quieten it when you pull into your house at 3am so as not to piss the neighbours or your family off. You can close it as soon as you see cops, so they're less likely to EPA you. Hell, I was late to an outdoor wedding recently and thankfully didn't have to disturb the wedding with my obnoxiously loud Exhaust when I pulled up.
Turbine with a hairdryer motor
Channel Page: http://www.youtube.com/user/mopatin/ Twitter: https://twitter.com/mopatin Google + : http://www.google.com/+mopatin This is a series of experiments with a 12 volt motor from a hairdryer. The hairdryer is 220 volt, but insted of using a transformer it uses the heat resistance in series to reduce the voltage to 12 volts and some diodes to rectify. That´s why these cheap hairdryers only run with hot air.
