"The DynoMax brandÔÇÖs dynamometer-proven performance advantage can be seen in recent side-by-side testing of Ultra Flo (No. 17263), Borla (No. 40600), Edelbrock (No. 5511), and Flowmaster (No. 42540) mufflers. The DynoMax Ultra Flo muffler delivered 1,000 cubic-feet-per-minute flow, compared to 846 CFM for the Borla, 579 CFM for the Edelbrock, and 352 CFM for the Flowmaster units, respectively.1
1 Flow rate measured at 20.3 inches H20. Tested mufflers were short-body, 2.5-inch side/center configuration units. Tests utilized side connection as inlet.
"
Everything else I found searching for flow numbers in google was Dynomax's own muffler versions being compared to each other
