take a look at the piece I unbolted from the tip of my exhaust...

Yikes, there must be a way to unplug this beast. There's wire mesh sloppily inserted at the end that must inhibit flow itself. Is that the spark arrestor? Don't really need one around here. Any ideas? Or is this muffler piece necessary as is for back pressure, etc. I know next to nothing about bike exhausts
Thanks,
