Holley is proud to announce the release of Hooker BlackHeart exhaust solutions for the '11-'14 Mustang GT. The BlackHeart line includes shorty & long tube headers, full catback exhausts, and axle-back exhausts as well. All Hooker BlackHeart products are constructed of lightweight, 18-gauge, 304 stainless steel material maximizing strength and durability, while tube geometry is designed for maximum ground clearance. All Hooker BlackHeart headers feature 3/8" laser cut header flanges for maximum strength and a perfect sealing surface. The long tube headers are available with 1 3/4" or 1 7/8" primaries and have long transition collectors featuring merge spears for increased exhaust velocity. Hooker BlackHeart exhaust systems utilize factory mounting points and can be used with either the OEM exhaust or BlackHeart headers. The exhaust tips feature a polished 4" dual wall design with a laser-etched Hooker logo. The mufflers that are available with the axle back exhaust and standard on the catback are also 304 stainless steel and feature a straight-through design to maximize performance gains. The axle back exhaust is also available without mufflers for those who desire an even more aggressive sound.
