Did the C3 ever have 2-1/2 exhaust manifolds? If not is there a 2-1/2 inch direct replacement?

I TOOK MY STOCK EX OFF & PUT HOOKER HEADERS WITH TRUE DUAL EXHAUST. BUT 2.5 MANIFOLDS ARE AVAILABLE. BUT ON THE 78 THE FRONT Y JOINS UP & GOES INTO A CATALYTIC CONVERTER THEN SPLITS INTO THE REAR Y PIPE.SO ITYS PRETTY RESTRICTIVE.

BUT 2.5 MANIFOLDS ARE AVAILABLE.

Anyone have a photo of a stock 2" 1978 exhaust manifold,,, Both LH and RH manifolds?
Or point me to where I can find a direct replacement for a 2" that shows me a good stand alone photo.
