To standardize airflow on its SuperFlow bench, Magnaflow flows mufflers through a 1.875-inch orifice— the maximum size that will allow the bench’s electric motor to produce 28 inches of water depression, which is the same standard used to flow cylinder heads. This is smaller than most people would use on a performance exhaust system, but it standardizes the playing field. Magnaflow’s 3-inch center inlet/offset outlet PN 14229 muffler as used on our system flows about 250 cfm at the standard depression on this bench. For comparison, the generic 2-1/2-inch mufflers we used with our smaller system flowed a mere 215 cfm, hence the cork effect. View Related Article
