My question is: is Summit AP_93102 the only choice for Y pipe. I can't marry the Y pipe with the manifolds. and NO i do not have the old exhaust.

 

what are you wanting it to do? do you need the cats?

 

I have new 3.0 engine, new manifolds (before 4/93. Truck built 10/92.) and the only y pipe I could find (Summit AP93102. The two will not fit. Seem like the passenger side is a 4" gap. There are 2 cats after the y pipe on the way to the muffer.
