The muffler is welded on, so you'd need to cut and weld a slip-on instead being able to just bolt it to the exhaust. If you want to do that, EMGO has pretty good options.

If you want a full system, then you'd have to shell out more $$$ and mess with your jets and carb.
Essentially it's not an "easy" exhaust to mod, but can be done if you have the tools and know-how. There's a thread on muffler replacement in the how-to section.
