Without the gasket you will leak air into your bore causing a lean condition and possible lean siezure.

No it will not effect compression until you melt the piston.

Just a thought - You may want to order a couple - they are cheap and you may end up taking your muffler off again (to change brake shoes, tire, etc.). I believe the manual recommends replacing it each time - probably could get away with re-use but it's nice to have a couple around.

I have ran without them. Just an exhaust leak, also reduces performance.

I've done it on dirt bikes jetted and mixed rich enough. It works fine then.
