Flow numbers on stock muffler?
Hi folks,
I searched and didn't find anything, so I'm sorry if this is a repeat.
Does anyone have flow numbers on the stock muffler? Is the turbo muffler the same as N/A? I'm most interested in the backpressure at 270 cfm, but I can work back from the more standard 25/28" H2O readings.
Thanks!
