| Hooker continues to push the boundaries of performance with the BlackHeart line of exhaust products. We are proud to offer this cat-back exhaust system for 2015-2017 Ford Mustang Shelby GT350/GT350R. This system retains the factory quad tips, and uses an x-pipe design to maximize performance and reduce in-cabin drone. It is built from 3 inch mandrel bent 304 SS for lightweight, strength and durability. The aggressive tone was achieved with dual 304 SS high flow, straight through design mufflers. All this produced Dyno gains of +21.07HP & +33.92 LB.FT. torque.
When it's time to tear the heart out of the competition - choose BlackHeart!
