Make your truck look and sound great with these MagnaFlow Black Series Diesel Performance exhaust systems. These particulate filter-back systems are constructed from mandrel-bent stainless steel tubing to keep the gasses flowing without excessive, power-robbing restrictions. The Black Series exhausts also feature a black ceramic coating that not only looks great, but helps to protect your exhaust system from the elements as well. Magna Flow dyno-tests these exhaust systems to ensure proven horsepower and torque improvements, while still maintaining a great sound. Each MagnaFlow Black Series Diesel Performance exhaust comes fully welded and built to last for years of headache-free service.
