Y Pipe, do I have a new one??
 

I checked under my 97 F150 to see if I had a new Y pipe or if it was still factory. I bought the truck a year ago. I measured the pipes coming from the cats and it was 2.5" and the inlet to my Flowmaster 50 was 3" I assume I have a new pipe. Is this correct. the duals were put on by a previous owner. Any ideas or comments are appreciated.
