I was wondering the other day, Is there a scale that the Muffler Industry uses to rate the flow of mufflers?


Seems like there is a flow rate for most systems but the exhaust.


I had experimented years ago with a shop vac and a ball in a tube but it was very rudimentary.


I should whip up a test stand again.
