From the mileage, I'd say unlikely: I had to replace mine at about half that much. But, from Sakamoto's website, it's possible. I'd write to inquire. If they only supply OEMs, they may affirm it, consider it extraordinary ,and want to inspect your car and even trade a new system for yours --which would be so cool as well as cheap.
They have an affiliate in Indiana:

Then again... they may supply Ann Arbor Muffler, midas, etc.
