Banks Monster Exhaust 48997 Details

Banks Power introduces the new 5-inch Monster Exhaust designed specifically for 2020-2023 Chevy Silverado and GMC Sierra 2500HD & 3500HD Duramax L5P pickup trucks. The DPF-back exhaust system features constant-diameter 5-inch mandrel-bent Aluminized Steel tubing and a massive patented tip which virtually eliminates backpressure after the DPF and prevents trailer meltdown.

Key Features

  • 5 inch constant-diameter aluminized steel DPF-back system
  • 15% reduction in exhaust temperature 2’ behind the tip during regen
  • 85% less backpressure than stock
  • 9% less backpressure at the exhaust turbine
  • Huge patented 6.5” × 7.5” ob-round slash-cut exhaust tip
  • Chrome-plated stainless tip will not turn brown with heat
  • Won’t void factory warranty
  • Fits trucks with aftermarket airbags
  • Does not fit Dually (Dual Rear Wheel) Trucks


The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through a process called regeneration in which scorching exhaust gas temperatures can last up to 20 minutes while driving. Unlike the stock Duramax exhaust which directs a prolonged jet-like blast of super-heated exhaust gas directly at anything being towed, the Monster Exhaust is aimed out to the side of the truck. This allows ambient air to diffuse the heated gas, eliminating the risk of melting a trailer, which has been reported by a number of Duramax owners.
