Show original supplier description
The Banks Power Monster Exhaust System is a 5-inch, DPF-back exhaust constructed from durable 409 stainless steel with a constant-diameter, mandrel-bent design. It is engineered to drastically improve exhaust flow and reduce backpressure, boasting an 89% reduction at the DPF and a 9% reduction at the turbine inlet. This enhanced flow allows the engine to operate more efficiently and potentially produce more horsepower. The system includes a large, 6.5" x 7.5" ob-round, slash-cut SideKick exhaust tip, available in either a polished chrome finish or a high-temperature Cerakote matte black. The unique SideKick tip design also contributes to a 15% reduction in exhaust temperature two feet behind the tip during regeneration cycles, mitigating the risk of damaging towed equipment. This Monster Exhaust System is designed to fit 2020-2022 Chevy and GMC 2500/3500 trucks equipped with the 6.6L Duramax L5P engine. It is specifically for Single Rear Wheel (SRW) configurations. The system fits Double Cab Short Bed, Double Cab Long Bed, Crew Cab Short Bed, and Crew Cab Long Bed models. However, it does NOT fit Single Cab Long Bed trucks, Dually DRW vehicles, or 2023.5 model year trucks equipped with Dual MAP sensors. It also does not fit 2024 and later model years.
