Thanks muaymendez1, that sounds good. I will go to the Honda store one day and see what they say. The copper wire wrapped around the pipe where the muffler clamps on may be good too.
Are you going to put the header wrap on before you put on the muffler to make a seal, or after, and wrap up the whole joint?
I remember buying muffler tape when I was young. Sort of a muffler bandage. Yeah, I think it was a muffler bandage.
