I put duals on my '36 coupe using a set of Fenton headers. The drivers side points down more than the French exhaust manifold shown, and it was still difficult to get the head pipe around the ('37) steering box. It's been almost 30 years, but it looks to me that the French manifold would be even more difficult to fit. I'm not trying to rain on anyone's parade, but there is a reason that the outlet on the Ford Police manifolds shown is not at the very back end of the manifold.
