The perfect choice for a variety of vehicles and engine applications, Flowmaster’s dBX mufflers utilize cutting-edge Laminar Flow technology drawn from both the HP2 and Pro Series mufflers to provide maximum performance and deliver a sound quality like no other. The key to its superior performance and smooth refined tone is the patented core design which delivers maximum exhaust efficiency, while at the same time minimizing the interior drone that is associated with other performance mufflers.
