ProTek RC 85mm Off-Road Exhaust Manifold (.21-.28)

The ProTek RC 85mm Off-Road Exhaust Manifold is a chrome manifold for .21-.28 applications. It includes two exhaust springs and is supplied with the ProTek 2100 tuned pipe.

This manifold can also be paired with the ProTek RC 2090 tuned pipe and used with other tuned pipe systems. At 85mm, it is 10mm longer than the manifold included with the ProTek RC 2090 tuned pipe. The longer design provides increased torque and bottom end, while a shorter manifold delivers smoother high RPM performance.
