Question hose size

Hardin Marine has some that look the same. They have the same advertising for the product. I measured my pipe when I took the mufflers out while doing some projects. Just did not measure inside. I am thinking its closer to 2 1/2".

The part number you showed me may not fit our exhaust hose. I am interested in more information.
I have a 94 prostar 205. The hose is 3" i.d. (inside dimension). The muffler inlet/outlet, starts at about 2 7/8" o.d., then increases in dimension. (for proper sealing)

To comfirm, I measured my old mufflers and a piece of exhaust hose.

good luck.
