The present-day Ford Shelby GT350 Mustang is a car whose stock exhaust note is truly beyond reproach. The even cylinder-firing of its 5.2-liter, flat-plane crank V8 lends the Shelby GT350 a loud, characteristic roar completely unlike that of any other domestic production car.
Even better, the factory exhaust comes with a pair of integrated butterfly valves, giving the driver the option of leaving them open to immerse himself in the full sound and fury of the engine at full chat, or turning the knob down to “civilized” when the noise gets to be a bit wearisome.
But what if one wants more out of the Shelby GT350’s already sterling bellow? For that person, there are the exhaust specialists at Borla, who’ve put together one of their trademark ATAK systems for Ford’s latest high-performance Mustang. You can hear it above, side-by-side with the factory exhaust for easy comparison.
Borla’s ATAK kit for the Shelby GT350 is a cat-back system that uses the factory exhaust tips, with no modifications to the rear valance required. It, too, has integrated butterfly valves, although even with the valves closed, it’s appreciably louder and more defined than the stock exhaust.
Pricing for Borla’s new Shelby GT350 cat-back exhaust kit is $2,239.99, according to the company website – money well spent for a few extra decibels of sonic bliss.
