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
. The individual product text and high-resolution images can be found on the individual product pages:
Polished tips w/o mufflers (Part # 70403306-RHKR)
