| GT Spec Exhaust Manifolds are designed and built to rigorous race specifications. The manifolds are constructed of highly polished SUS 304 piping and are TIG welded for durability and strength. The collector pipes at the exhaust ports are deburred and hand-ported for optimal exhaust flow. The 4-2-1 design is used for high horsepower gains without sacrificing mid-range torque like most 4-into-1 configurations. | ![]() |
