Put on your earphones and turn up the volume.
Do you have a Karen in the neighborhood constantly groaning about the noise your car makes? Would you like the exact revenge on said Karen?
Look no further than the Hennessey Mustang Shelby GT350R, which is being punted again on Hennessey's YouTube page.
We weren't sure why Hennessey was making a big deal about this car again, as this upgrade package first surfaced in 2015, packing 808 horsepower and 657 lb-ft of torque. A glance at the latest figures on the website shows that the power output has increased to 858 hp at 7,700 rpm and 4,600 rpm.
It boasts an impressive list of upgrades, but listen to the noises this car makes before we get to that. Simply turning it on in the mornings will result in every Karen within a one-mile radius spontaneously exploding. Don't believe us. Check out the video below and turn the volume way up. If you're a Karen, you'll want to look away at this point.
The standard GT350 is already a spectacular machine and will definitely go down as one of the most iconic Mustangs in history. It comes equipped with a 5.2-liter Voodoo V8 with a flat-plane crank, which means it can spin all the way to 8,250 rpm. The result is 526 hp in the standard GT350 and 527 hp in the lightweight GT350R.
That's not even the most impressive thing about it. The Mustang Shelby GT350 was built for the track and features several upgrades to help it string together a series of corners properly. Our assessment was basically that the car was perfectly balanced, offering just enough power not to be scary.
The problem is, you get used to a car over time, and you eventually find the limit. So you want more power, and that's where Hennessey comes in.
Hennessey adds a 3.0-liter supercharger, a high-flow throttle body, fuel injectors, heat exchanger, and air induction system. Obviously, the installation is done by professionals, and Hennessey will drive it for up to 400 miles to ensure everything is in working order.
Other additions include an interior plaque with a serial number and another plaque under the hood. You also get Hennessey floor mats and a two-year/24,000-mile limited warranty.
The best thing about it is the noise, however. It's gloriously offensive, and the only car we can think of that sounds better is the Novitec Ferrari F12 with straight pipes.
If you wanted to listen to the Hennessey Mustang Shelby GT350R one more time, here's a video proving that it puts nearly 800 hp through the rear tires.
