If you're looking for an exhaust system that will give you more power and better performance, look no further than the Banks 49779 5 Inch Single Monster Exhaust System. This system is designed for the 2010-2012 6.7 Cummins engines and virtually eliminates backpressure after the DPF, so you can enjoy more power and better fuel economy. The constant-diameter 5" mandrel-bent aluminized steel tubing provides less backpressure than stock, while the huge patented 6.5" x 7.5" ob-round slash-cut exhaust tip gives you a deep, throaty sound that will turn heads. The chrome-plated stainless tip will not turn brown with heat, so you can enjoy good looks and great performance for years to come.
