Holley is proud to announce the release of the Hooker BlackHeart axleback exhausts for the 2015 Ecoboost Mustang.

The Hooker BlackHeart axleback exhaust for the 2015 Ecoboost Mustang is a premium product that maintains a great price. It is constructed of 2.5" lightweight 18-gauge 304 stainless steel to maximize strength and durability. The exhaust features quality welds throughout for strength, longevity, and good looks. They are available with either a straight-through muffler or no muffler design that exits into either 4" dual wall polished stainless steel tips or satin black powder coated tips, both laser-etched with the Hooker BlackHeart logo. Tube geometry is optimized for maximum ground clearance and retains the use of factory mounting points for a hassle-free installation.

With the Hooker BlackHeart axleback exhaust, we have seen maximum gains of 5.22 horsepower and 4.55 lb/ft of torque with mufflers, and 15.63 horsepower and 13.75 lb/ft of torque without mufflers.
