From the jump we wondered how a free-flowing exhaust might wake up the performance of the highly tuned 5.2-liter engine that powers the latest Shelby GT350. Now that the cars have been on the streets for a while, the aftermarket mods are starting to flow, and one of the newest exhaust products is American Racing Headers’ system, featuring long-tube headers and a high-flow midpipe.

The American Racing Headers exhaust system for the Shelby GT350 features long-tube headers constructed of .065-inch-wall tubing. It is available with either and X- or H-shaped crossover and with or without catalytic converters. In the case of Dillon’s GT350, he opted for the X-pipe sans cats. All versions of the system are designed to join with the factory active mufflers.

One of the early adopters of this system was SVTP member Dillon Dollar, who brought his Shelby GT350 to True Street Motorsports in McKinney, Texas, to have the car upgraded with the exhaust system and more.

“No one had actual numbers on the ARH system yet and I’ve used them in the past on my 2013 GT500,” Dillon said of his exhaust choice.
