Mufflers for '79 1300

Am restoring a project bike and the mufflers are rotten. Would like to get stock ones, but the ones from Kawi are 900 CA$ and I am not yet prepared to put the fancy 6/1 header on her yet. Does anyone know of a universal fit slip on that might fit in the interim?

Thanks

Len

Check this place out, it's quite amazing. 1300

Am aware of the site. David has been a great help to me thusfar in my rebuild.
