Official Release:

Holley Performance Products is proud to announce their new Hooker Blackheart catback and axleback exhaust systems for the 2015 Ford Mustang GT equipped with the 5.0L Coyote V8. Both systems are available with or without mufflers.

The Hooker Blackheart catback and axleback exhausts for 2015 Mustang GTs are constructed of lightweight 18-gauge 304 stainless steel to maximize strength and durability. The 3″ diameter exhaust and straight through muffler design work together to increase exhaust flow and produce an aggressive sound while on or off the throttle. The 4″ dual wall polished 304 stainless steel tips are laser-etched to give the exhaust the perfect look to backup the sound and proven dyno-proven gains. These exhausts still utilize the factory exhaust mounting points for ease of installation. The tube geometry is designed for maximum ground clearance and hassle free installation.

Average gains of 8.81 horsepower and 10.62 lb/ft of torque can be seen with the axle back without mufflers, while average gains of 9.39 horsepower and 11.6 lb/ft of torque can be seen with the catback without mufflers. Peak gains for the axleback are 16.01 horsepower and 6.91 lb/ft of torque, while the catback shows peak gains of 13.73 horsepower and 4.4 lb/ft of torque. These tests were performed on an otherwise stock car.
