Connecting Exhausts for a V8 Se5 Scimitar...
Tom's car uses (like my original 3.5 in the SE6) two Land Rover drivers side 4-1 cast iron manifolds. In fact, they were mine... This setup allows you to attach your downpipes with minimal modification (it helps to have the male end of the Range Rover pipe to mate with the manifold - scimitar I think is female).
See my exhausts page for an SE6 tubular V8 setup, as soon as someone comes up with an SE5 solution I'll post it here. It may even be that my SE6 ones would do - but they ain't comin' off in the near future!
