Banks Power's Monster Exhaust System for GM Duramax L5P

Banks Power proudly presents the new 5-inch Monster Exhaust System, meticulously crafted for the 2020-2023 GM 2500/3500 L5P Duramax HD pickup trucks. This innovative exhaust system is designed to revolutionize the performance and aesthetics of your Duramax truck. With its DPF-back design and massive patented tip, the Monster Exhaust System offers unparalleled backpressure reduction and enhanced performance.

Significant Performance Enhancements

The Monster Exhaust System boasts a constant-diameter 5-inch mandrel-bent Aluminized Steel tubing, which provides a massive 192% greater flow area compared to the stock exhaust nozzle. This substantial increase in flow area results in 85% less backpressure, leading to a significant boost in power and improved fuel economy. The system's unique design virtually eliminates the risk of trailer meltdown, making it an ideal choice for heavy-duty towing applications.

Exterior Appeal and Durability

Not only does the Monster Exhaust System deliver exceptional performance, but it also enhances the visual appeal of your Duramax truck. Available in two sleek options – chrome-plated polished stainless steel or high-temp matte black – the patented 6.5 x 7.5-inch ob-round slash-cut exhaust tips offer a distinctive and stylish look. The chrome-plated stainless tip will not turn brown with heat, ensuring a long-lasting finish. Additionally, the system provides a 15% reduction in exhaust temperature two feet behind the tip during regeneration, further improving the efficiency and safety of your truck. Key Features:
  • 5" Aluminized Steel constant-diameter DPF-back exhaust system
  • 15% reduction in exhaust temperature 2 feet behind the tip during regen
  • Huge patented 6.5" x 7.5" ob-round slash-cut exhaust tip
  • Chrome-plated stainless tip will not turn brown with heat
  • 85% less backpressure than stock
