The 50 Series Heavy Duty Muffler is appropriately named, a tough customer just like the trucks it was designed for. With 4.00-inch internal components and 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 and diesel applications, and late-model trucks used in the most extreme working conditions. They are constructed of 16-gauge steel and fully MIG-welded for maximum durability. Stainless models carry a limited lifetime warranty
