I have a 1969 new yorker with original exhaust manifolds 2562464 on the right side and 2463107. everything i lookup says those part numbers should be a 2 1/4 outlet, I bought a new stock exhaust system and it is 2 1/4 flanges. The problem is my exhaust manifolds I have are a 2" discharge outlet??? Is this correct? It was originally a "Y" pipe to a single exhaust.
