DNA's Truck Series Mufflers are designed for trucks and SUVs. Theses mufflers have a deep, throaty sound and increase horsepower and mileage. The stainless design eliminates carbon deposits in diesel applications. Made from lightweight B2 stainless steel these mufflers feature NO packing or perforated tubing to blow-out. The exhaust noise is controlled by patented deflectors that are fully welded. Each muffler has a vent tube that was designed to dissipate the extreme temperatures created by exhaust gases, which improves the longevity and efficiency of the muffler.
