There is little doubt that the 5.2-liter Voodoo engine in the latest Shelby GT350 exhales with the best exhaust sound of any factory Mustang. This is especially true of the resonator-free R-model with its exhaust valves in the open position. Yet with all the airflow scurrying through the engine at 8,250 rpm, we had to wonder if long-tube headers and a freer-flowing exhaust would unleash even more power from this flat-plane-crank V-8.
Recently the exhaust experts at Kooks let out a teaser video of the companyâ€™s freshly minted 1 3/4- to 1 7/8-inch Step Headers, a pair of 3-inch Front Connection Pipes with Green Cats, and a 3-inch X-pipe mated to the factory axle-back and mufflers. They followed that up by rounding out the system with one of the companyâ€™s own axle-back systems featuring Kooks mufflers.
Now the dyno results from this upgrade have hit the Internet. You can watch Joeâ€™s car run on the dyno at Roush Yates right hereâ€¦
