This is my first post here, but have been visiting for a few years now. My bird had a set of exhaust manifolds on it that looked like headers to me. They only had three pipes that went into the collector though. The two center cylinders shared a pipe. At first glance, someone asked if that was a V6. I knew better. Is this some kind of production manifold or did it just end up on this car? I have since replaced them with a set of Hedman Headers, but am curious to know what they are. Can anyone provide some info?
