Testing the varex muffler out on a 12A bridgeport rotary engine on idle. Closed, the Db level will reach around the 100 mark on throttle. Open it will exceed 120 Db on throttle.

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.
Part 12: 13B Rotary Engine Rebuild - My 76 Mazda RX-5 Cosmo Restoration
Just as I promised last episode, it is finally time to build the engine! Part 12 of my RX-5 Cosmo restoration covers the entire process of building the 6 port 13B Mazda rotary engine. While this engine is a hybrid of GSL-SE RX-7 and Cosmo parts, the process is the same for any rotary from a 12A to a 13B NA, 13B turbo, 13B-REW or any other variant of the 13B. This video shows the whole process of the engine build, starting from measuring the rotors and covering everything else including clearancing the side seals, assembling the rotors, complete assembly the short block, setting the eccentric shaft end play and installing the front cover and everything underneath it. It's probably the most complete engine build video outside of what you can buy from the vendors, and as such, is an hour long. After this one, I'm going back to videos under 20 minutes. But for now, grab a beverage of your choice, sit back, and enjoy.

Yearly Hillclimb in Teuven (Belgium) with a lot of different cars but here is just a clip of my friends 1980 RX-7 SA with a 12A bridgeport.
The smoke doesn't mean it's broken, the rotary is being premixed.
Missile Car Drifting In Driveway
US Formula drift driver Ryan Tuerck strapped Tim Brodhagen, the host of Network A's "dose," into his practice vehicle aka "the missile car" for a wild ride down his sketchy driveway to give him a taste of what drifting is all about. Once the dust settles Ryan gives Tim the breakdown of how he defies both mechanics and logic for one hell of an adrenaline rush.
