A downpipe didn't come with the headers on my 3000gt, I assumed they were seperate on this engine too. I don't think the way the pipe curves around from the rear bank is a great design. I was looking for something a little more strait.

It looks like the down pipe is the weak link. I think a well designed down pipe could yield 75%-85% of the gains of a header, unless there is some glaring flow issue with the manifolds. If I get motivated I'd make one. But, headers are so dirt cheap, except the CTs.
