Holley Expands Hooker BlackHeart Exhaust Products for New V6 Ford Mustang

Mar 8, 2016

Holley is proud to announce the release of new Hooker BlackHeart exhaust components, including axle-back exhaust systems, cat-back exhaust systems, and longtube headers for 2015-16 Ford Mustangs equipped with the 3.7L V6.

Hooker BlackHeart’s cat-back exhausts for 2015-2016 3.7L V6 Mustangs are built from 18-gauge 304 stainless steel for added strength, long-lasting looks, and maximum performance., according to Holley. The 2-1/2 inch diameter, incorporated H-pipe, and high-flow, straight-through mufflers combine to create max dyno gains of 12.47 horsepower and 20.27 lb/ft of torque with mufflers, and 11.65 horsepower and 15.62 lb/ft of torque without mufflers.

Tubing geometry is optimized for maximum ground clearance, and the systems are designed to utilize factory mounting points for ease of installation. The 4″ dual wall, angle cut, polished 304 stainless steel tips are laser etched with the Hooker BlackHeart logo.

Hooker BlackHeart also offers axle-back exhaust systems. Replacing the factory axle-back yields max dyno gains of 9.07 horsepower and 14.54 lb/ft of torque with mufflers and 8.93 horsepower and 13.05 lb/ft of torque without mufflers. The axle-back has all of the same features as the cat-back, meaning that it employs 2 1/2″ 18-gauge 304 stainless steel construction, utilizes factory mounting points, and has the same polished 4-inch stainless steel tips that are laser etched with the BlackHeart logo.

Hooker BlackHeart has also designed a set of longtube headers for 2015-16 V6 Ford Mustangs. They are built from the same 18-gauge, mandrel-bent 304 stainless steel used in the cat-back and axle-back exhausts. The headers feature 3/8-inch thick water-jet cut flanges for the truest, highest quality sealing surface possible. The primaries measure 1-5/8 inches in diameter and the collectors are 2-1/2 inches in diameter. These components are hand-welded for long-lasting quality, according to Holley. The headers also include high-quality oxygen sensor extension wires to speed up installation. The headers are designed to work with a matching BlackHeart race exhaust system.
