A drop-in stock installation, stock looking replacement that is anything but stock! The larger Ballistic Billet compressor wheel and our new exclusive Low MOI QST turbine wheel results in reduced backpressure, quicker response, increased efficiency and increased turbine flow compared to the competition. 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. Perfectly paired with a pulse manifold made from high-silicon ductile iron and designed to withstand extreme temperatures and vibration. Precision slip joints allow the manifold to expand and contract, which reduces cyclic thermal fatigue and greatly increases manifold longevity.
