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. All BlackHeart headers are constructed of lightweight 18-gauge, 304 stainless steel with high flow, long transition collectors featuring merge spears for maximum flow and increased exhaust velocity. 3/8" thick laser cut flanges provide maximum sealing surface for a leak-free seal and ultimate strength. The primary tubes are designed for optimum flow and maximum ground and engine component clearance providing the perfect combination of performance and fit. When it's time to tear the heart out of the competition – choose BlackHeart!
