RE: 'TO USE' or 'NOT TO USE' a Support Strap/Bracket on a Wrap Around Pitts Muffler?
The Support Strap should actually be on the other end of the Muffler, the muffler is already supported at the exhaust port, it needs support on the other end where it is not attached to anything; unless it does have a 2nd one on the othe side not shown in Picture.
