Can this be repacked or is it a sealed system? Also, will it get louder overtime if packing burns off?

Does it allow access to the chain tensioner?

Yes our muffler allows better access to chain tensioner than the stock muffler. This is a chamber style muffler so you don't have to worry about burning anything off.
