ADDED TO YOUR CART!
Headers, Husler LS Swap, 1973-77 A-Body, 1-7/8"x2" Stepped Long-Tube
ADDED TO YOUR WISHLIST!
These STEPPED long tube LS swap headers fit 1973-1977 GM A-Body cars. They have a 18-gauge mild steel construction, and use smooth flowing, 1-7/8 in. x 2 in. diameter STEPPED TUBES that provide higher torque across the entire RPM range. The smaller tube diameter at the exhaust port increases back-pressure at low-RPM to improve low-end torque from the line, or out of the corner, while the larger diameter tube segment produces more torque as you reach Wide-Open throttle. The stout 3/8" header flanges ensure a great seal that will resist warping, and the high-flow 3 inch race collectors ensure unimpeded exhaust flow for maximum performance. Includes gaskets and hardware.
