ProTek RC 85mm Off-Road Exhaust Manifold (.21-.28) (PTK-2546)

This is the ProTek R/C 85mm Off-Road Exhaust Manifold. This chrome manifold includes two exhaust springs. This manifold is included with the ProTek 2100 tuned pipe, but produce great results when paired with the ProTek R/C 2090 tuned pipe, and can be used with other tuned pipe systems as well.

This 85mm manifold is 10mm longer than the manifold included with the ProTek R/C 2090 tuned pipe. The longer manifold will provide increased torque and bottom end, while a shorter manifold will create smoother high RPM performance.
