Holley is pleased to announce the release of Hooker BlackHeart C5 Tri-Y Long Tube Headers. Made from mandrel-bent 304 stainless steel for maximum strength and durability and designed specifically for 5.7L C5 Corvettes, they're available in two versions – one for 1997-2000 C5s and one for 2001-04 models. These full-length headers feature a special Tri-Y design for a broad torque curve and excellent horsepower, are 100-percent hand-welded, and eliminate the need for oxygen-sensor extensions.
They accept stock air-injection manifolds, feature optimized tube geometry and 1-7/8” primary tubes with 3” collectors, come complete with all the necessary fasteners, and are ready to bolt on with no fabrication or modifications. They also feature 3/8'' CNC waterjet cut header flanges for strength and to offer the best sealing surface possible.
