Ah, I see the confusion. The ones in the pictures above are from Precision Proformance
(Byars) and are 4-into-1, not tri-y. They are coated and are the headers we are
currently running on the A3 heads.
These are the stainless tri-y's (dusty but should shine up):
They will be used on the smaller exhaust port C3/C302/C302B heads only as the port
size at the flange (1 3/4" OD primaries) is too small for the large A3 exhaust ports.
The merge I'm using came from Verocious Motorsports (from Kelly's header building post)
and is designed to slip over two 2" OD pipes and has a 2.5" outlet (same as the inlet
to my Magnaflow mufflers):
It needs about 14" of dual 2" leading to it to make it a real tri-y. It originally
had two 2" pipes leading to dual mufflers per side. Kirk didn't think it would fit
the Pantera as originally fabricated. I still need to mock it up in the red Pantera.
