I recently replaced my fubar-rusted stock mufflers with short lengths of 1-1/2" o/d exhaust pipe welded to the stock headers and a pair of Triumph mufflers I bought for $35 at a swapmeet.
Here are the close-up photos:-

The Triumph muffler brackets bolt up exactly onto the stock XS11 muffler attachment points.
I had to ball-pein hammer a groove into the top of each muffler to clear the XS11's cast aluminum footpeg brackets but they don't show.
And oh boy, what a lovely note. But that and the improved performance are likely due to the exhaust gases not leaking out of the original mufflers' cracked welds any more.
