MagnaFlow's Wide Open Performance Mufflers outflow OEM chamber style mufflers by as much as 167 percent. This reduces engine heat and backpressure and improves exhaust scavenging from the combustion chamber. MagnaFlow minimizes the power robbing effects of the OEM system to restore torque and horsepower to the engine.
