note: our highest flowing 5" muffler is the 7018-115AL (955 cfm at 7" of H2O), but this muffler and the 7014-115AL are our most aggressive sounding 5" mufflers. The # 7088Q (768 cfm at 7" H2O) has a lower flow rate, but is quieter than the 7014-115AL and the 7018-115AL. The 5024-114AL is our highest flowing and loudest 4" muffler, followed in order of lower flow rate and lower exhaust sound by the 7014-114SS, 7081W (603 cfm at 7" H2O), 7081Q (353 cfm at 7" H2O), and 1977. For reference, in our testing, the well-designed O.E. factory muffler on a 2004-1/2 Dodge Ram 600 3500 w/5.9L turbo diesel engine flowed 433 cfm at 7" of H2O.
