Getting ready to put my y-pipe back up to the manifold on my 1991 Z28, L98 car. y-pipe has a female flange opening, and the manifold end is flat. So ive been looking around and think i found what i need.

i know the auction is long over but i got the part number from it. 14055405

one of the previous owners had jacked up the y-pipe to bypass the 2nd cat. and managed to weld the pass side downpipe right into the drivers side pipe that crosses under it. the gasket flange that came out was in 2 pieces.

will i be set if i pick up this part? ill try for pictures of my y-pipe tomorrow.

Did you ever find your answer? I've been going crazy over this same problem for the past week. Is there some type of adapter?
