Born with an dual-mode exhaust from the factory, the Shelby GT350 is already one of the best sounding Mustangs ever built. Thatâ€™s especially true of the R-model, which doesnâ€™t wear resonators before the mufflers like the standard Shelby does. But it could always sound better, right?
Lethal Performance has already taken its GT350 project over 800 rear-wheel horsepower with the addition of a Whipple 2.9-liter supercharger, but that was with the factory cat-back exhaust in place. To free up some exhaust flow and rev up the carâ€™s auditory personality, the company chose to upgrade the exhaust with Magnaflowâ€™s cat-back system (PN MAG-19283).
