FLOWMASTER 50 HD HEAVY-DUTY Muffler

The 50 Series heavy-duty muffler is appropriately named, a tough customer just like the trucks it was designed for. With 4 inch internal components and a large case size, these mufflers help to significantly increase mileage, torque, and horsepower while greatly improving towing power and acceleration. The 50 Series heavy-duty is great for gas, diesel, and late-model trucks used in the most extreme working conditions. They are constructed of 16-gauge steel and are fully MIG-welded for maximum durability. Stainless models carry a lifetime limited warranty.
