It's no thanks to coffee tin fart cans buzzing around the neighborhood that aftermarket exhausts get a bad name, but when the custom work is done right, the effect is profound. So much so in some cases that it's like taking Luciano Pavarotti out of a broom closet studio and putting him center stage at the Teatro alls Scala in Milan. Such is the work of aftermarket tuners like Novitec, which finds a way to make the noise coming out of a V12 Ferrari engine somehow better.

However in this case, it's not the exhaust pipes that make the already great-sounding Ford Mustang Shelby GT350R sound the way it does, it's the modifications Hennessey has made to the engine. With this HPE850 upgrade, Hennessey adds a 2.9-liter supercharger to the naturally aspirated flat-plane crank Voodoo V8 in order to extract almost 800 horsepower.

The effect it has on performance is intense, but the only thing that's arguably just as good is this exhaust note. Thanks the this 'Stang's angry design, it already looks like it's going fast even when standing still, but the real drama starts when the driver mats the throttle, giving us the impression that the GT350 is cutting through the wind and its opponent's hopes and dreams at a pink slip at the same time. Life's simple pleasures don't have to be few and far-between, and thankfully Hennessey's YouTube channel shortens the gap.
