RE: 'TO USE' or 'NOT TO USE' a Support Strap/Bracket on a Wrap Around Pitts Muffler?
First, I've never had a Jtec muffler fail. Second, you've got the engine moving around slightly on the end of those stand offs, so the muffler is moving around with it as well. Now, bolt the end of that muffler to something that's NOT moving, or maybe moving at a different frequency, and what have you created?
