I have a Apex world sport. I think something in the muffler may have broke and causes a rattle at certain RPM's, anyhow If I was to make it straight through how would I go about doing it? ramming a pipe in there? any suggestions?

You have an exhaust leak, go reinstall gaskets.

It's something inside the can, maybe the chambers rattled loose? gaskets are good.
