Holley is proud to announce the release of Hooker Blackheart axleback and catback exhausts, as well as shorty and longtube headers for 5th Generation Camaro SSs equipped with the 6.2 liter LS3 and L99 engines. All Hooker Blackheart products are constructed of lightweight, 18-gauge, 304 stainless steel material to maximize strength and durability while tube geometry is designed for maximum ground clearance and improved flow characteristics. All Hooker Blackheart headers feature 3/8" precision water jet cut header flanges for maximum strength and a perfect sealing surface. Both the long tube and shorty headers are available with 1 7/8" primaries while the longtubes utilize long transition collectors featuring merge spears for increased exhaust velocity and scavenging. Hooker Blackheart exhaust systems utilize factory mounting points and can be used with either the OEM exhaust or Blackheart headers. The exhaust tips feature either a polished 4" dual wall design with a laser-etched Hooker logo or a quad tip option for NPP-optioned cars with the factory dual mode exhaust. The mufflers that are available with the axleback and catback exhausts are also constructed of 304 stainless steel and feature a straight-through design to maximize performance gains. The axleback and catback exhausts are also available without mufflers for those who desire an even more aggressive sound.
