Yup, it’s possible to improve upon the Corvette C6 and C7. Even with their looks, performance and sheer amount of horsepower from the factory, the OEM exhaust is certainly a point of interest for many enthusiasts. With so many options out there, it can be tough to decide upon a specific system. Holley Performance Products has recently addressed this, thank to their new line of Blackheart exhaust systems for the C6 and C7 Corvette! Larn more about them below!
Official Release:
Holley is Proud to Announce the Release of New Hooker BlackHeart Exhaust Products for C6 and C7 Corvettes.

All Hooker BlackHeart products for C6 and C7 Corvettes are constructed of 18-gauge 304 stainless steel, which is meticulously hand-welded by the BlackHeart team in Bowling Green, KY for strength, longevity, and good looks. Tube geometry is designed for maximum ground clearance and a hassle-free installation that utilizes the OEM exhaust hangers. Exhaust systems are available with no mufflers, high-flow straight through mufflers, or dual mode mufflers designed to work with GM’s factory NPP valve actuator. The exhaust then exits through 4-inch dual wall polished 304 stainless steel tips that are laser etched with the Hooker BlackHeart logo. To see the dyno proven gains of each system, CLICK HERE.

The C6 Z06 longtube race headers feature 1-7/8″ primaries and 3″ long transition collectors with merge spears for maximum flow and increased exhaust velocity. For more radical applications, the C6 Z06 Tri-Y headers feature huge 2″ primaries, 2-1/4″ secondaries, and a 3″ collector.

The C7 Z06 shorty headers utilize 1-7/8″ primaries that merge into a unique 4-1 collector for excellent scavenging and a compact design that works with the factory exhaust system. This design is up to 19 pounds lighter than the factory cast-iron manifolds and has shown power gains of 14 horsepower and 12 lb/ft of torque.

All BlackHeart headers use 3/8″ thick precision water jet cut flanges and include all necessary hardware and O2 sensor extension harnesses.
