Stainless Steel Muffler
Tell me how to be sure that a muffler is Stainless steel. I am tempted to buy one used 911 muffler , owner says it is SS , but was not sure.It is looking like any muffler , some surface rust was visible.Not much.
Any markings or something like that , to tell that it really is SS? Or any other method of testing it?
