Stock CJ Exhaust size?

I am shedding the duals and going back to a single exhaust. What is the stock pipe size? I think it was 2.5"

The PO who installed the duals put 2" pipe in. If I take off one side, will using the 2" pipe on the driver's side be a flow problem?

I am probably going to put on a Hedman 6 into 1 header. It has a 2.5" diameter at the collector.
