Has anyone seen this before or tried to make a true duel exhaust from scratch?

Because of the clearance on the driver side, would a LOG type header still be an improvement in flow over the stock crossover style manofolds?

That driver's side is a harrowing place. Only things I know is the factory dual exhaust manifold and a real trrick set of headers. You know where to get the header parts. Anybody got a spare manifold? I'm out of spares myself.

 

A spare true dual driver side header would be nice... good luck finding one... or affording one...
