Exhaust for piaggio typhoon 125

I am looking for an aftermarket exhaust for piaggio typhoon 125 2013, as the current exhaust is not in good shape (i bought it this way). most places i look don’t have anything listed as compatible, and a new stock exhaust is ~$600. does anyone have experience/suggestions? I was thinking the sito plus for vespa lx150 might fit.

any other suggestions for this scooter, regarding maintenance, suggested upgrades, really whatever are welcome. im not the most mechanically inclined, but im learning.
