4.0 exhaust question-headers?
So, I was just informed that all 4.0 engines came with headers from the factory, is this true?
Not true - the 4.0 had an exhaust manifold. Yes, it's tubular in nature, giving some the impression that it's a "header." However, the tubing is not tuned in length, nor are there any collectors, and thus it's simply a manifold, not a header.
