5" aluminized steel constant-diameter DPF-back exhaust system with patented negative-backpressure SideKick tip which virtually eliminates back pressure after the DPF. Allows the engine to exhale and breathe more efficiently.
With the stock exhaust measuring a mere 4" compared to the Monster Exhaust's massive 5" outlet, the Banks system offers a 60% greater flow area than stock, and the Monster Exhaust boasts less backpressure than stock, leading to more power and increased fuel economy.
Cummins owners can choose from two huge patented 6.5" x 7.5" ob-round slash-cut exhaust tips; chrome-plated polished stainless steel or high-temp matte black with a rolled edge. And, unlike other brands, Banks' chrome-plated stainless tip will not turn brown with heat.
