A drop-in stock installation, stock looking replacement that is anything but stock! This results in increased maximum potential power output, right up to 690 horsepower with supporting modifications. No extra parts to install, just drop-in and enjoy the extra power potential. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increases manifold longevity.
