While you’re there, take a tour through his workshop and see the project cars.
You can play the 24-minute video by clicking on it above. It opens with Leno’s GT making some great noises. Leno demonstrates the system at the 13-minute mark. Heffner Performance made it. As the screenshots below show, it completely eliminates the stock GT’s muffler. It’s very light, only six pounds according the video. The supercar has a quick sound. You’ll see more of Leno’s GT revving when you get to the 23.10 mark. This is definitely a noticeable improvement over the stock system
You’ll be missing a lot of fascinating car content if you just focus on these Ford GT moments. This is a shame as it appeals to both shade-tree mechanics, and collectors of rare motoring equipment. Although the 1968 Pontiac Firebird isn’t uncommon per se, it is unique because it has a factory-inline-six engine. We then learn about Kleiber, a San Francisco manufacturer that built sedans on truck frames in the 1920s.
However, the majority of the video is dedicated to steam. We are treated to two restoration projects that Leno is currently working on. One of the projects, a Doble steamcar, is being mocked up in order to show how the direct-drive four cylinder steam engine works. It’s true, it’s car-nerd territory, but it’s absolutely amazing. It’s okay to admit it.
A 1914 electric car is also shown, along with Nissan Leaf battery and a banging stereo system. Another obscure American car, a 1920s model that needs custom-fabricated parts and an MG that looks like a bag case, is also on display. Jay Leno’s Garage is just another day.
