Can I get a muffler clamp that will work with stock muffler from Lowes, Ace or Home Depot? Is 2" OD what I need?

Maybe a 2" OD T-Bolt stainless steel clamp?

Well,whether or not something is defiant or not,we have to make it work. If it works defiantly ,it still works.
T-bolts aren't available everywhere,but they're not rare,either. I can get them at the local commercial bearing supply. They are the only type of clamp I'd consider on a bike.
