Original RS2000 Exhaust Header V extractors
Many years ago, I collected a couple of RS2000 exhaust manifolds. I am now rebuilding my RS2000 and am pondering either a new set of extractors or putting the RS2000 cast manifold onto it. For reference the RS manifold was a double outlet cast item, from which a set of secondaries would run to under the car before joining to a single pipe.
My engine runs twin IDF's, head work, and a large Ivan Tighe Cam.
Not planning to race it once finished, so a few HP down wont bother me, losing 30% would. Anyone with experience, I would love to hear it.
