At the heart of any performance vehicle is the exhaust system. Hooker with its classic heart logo has been at the core of the exhaust industry for decades. Many of the most powerful vehicles on the planet have used Hooker Headers. Hooker continues to push the boundaries of performance with the new BlackHeart line of performance exhaust systems for popular late model vehicles. The BlackHeart line is truly a platform designed full exhaust program. From the cylinder head flange to the tailpipe, the BlackHeart line is engineered to provide maximum exhaust velocity, ground clearance, style, performance, and quality!
