The Mustang Shelby GT350 has received metric tons of appreciation ever since it swiped us off our feet on the 2015 Detroit Auto Show floor, but certain aficionados explain the soundtrack of the muscle Ford is simply too raspy for them.
While we can't deny the aural difference from the traditional American V8 burble, this is the obvious effect of the flat-plane crank and the firing order that the 5.2-liter VooDoo under the hood uses. While we adore the melange between the Coyote soundtrack and the high-revving scream of, say, a Ferrari, this is one of those de gustibus non est disputandum cases.

However, we wanted to show those who point their fingers at the GT350 over its voice that things can get noticeably raspier, especially when an aftermarket touch is added to the 5.2-liter V8 motivating the wild pony.

The VooDoo-engined 'Stang in the clip below has been touched by Kooks Exhaust. The company installed a set of long headers that only set the voice of the GT350 ever further apart from that of a cross-plane V8 such as that used by the Mustang GT.

While their headers were displayed at last year's SEMA event, we didn't get a chance to listen to their effect. Things have now changed, with the hardware now being fitted to a customer's vehicle.

Let's get into the details of this custom exhaust setup

We're talking about a setup that implies Kooks' 1 3/4- to 1 7/8-inch step headers, a pair of 3-inch front connection pipes with green catalytic converters, and a 3-inch X-pipe linked to the factory axle-back exhaust.

The tuner released the video below, which allows us to get a taste of the aural action. Keep in mind that the GT350 does hit the rev limiter here, bouncing off quite a bit due to the aggressive launch.
