That gasket can be still used, try using high heat exhaust gasket silicone or hhigh heat RTV silicone I have use gasket that have been bent and missing lots more and it seal without leaking.
I just paid $12 for a part that is damaged and I think I will wait for a new one. The bike will be all put back together and not run until spring. Don't want to find out during riding season that it needs to come apart again. Will keep you posted on my progress. Thanks for all the help and advise.
Got my new gasket and dropped the muffler and pipe. Rear exhaust gasket was almost completely gone. There was only about 15% of the gasket left on one side. Will put pipes back on in a few days.
