Holley/MSD is pleased to announce the expansion of Hooker Headers' vast line of performance exhaust systems, which now includes RacingHeart Headers. Available in both chrome-plated mild steel and polished 304 stainless steel, RacingHeart Headers' down-swept configuration is ideal for big-block Chevy-powered dragsters. These three-step headers feature 2.125-2.250-2.375-inch stepped primary tubes and 4.500-inch collectors with merge spears to maximize exhaust flow and velocity for horsepower and torque gains across a broad rpm range. Sturdy 3/8-inch flanges provide strength and sealing, and bungs for evac systems (and even the evac tubes and plugs themselves) are included.
