i have a source that says doug thorley is looking at producing a legal set for our vg33's.
a buddy of mine made some headers with some bent pipe and the factory flange for the exhaust.

it was for a pathy 3.0. not sure how this design would work for our 3.3's, there are more electronics involved with ours.
newer headers seem to be designed with cylinder firing order in mind for optimum flow, as opposed to the old "the better it breathes, the better it runs" way of thinking.
