Banks Monster Exhaust 48996 Details

Introducing the new Banks 5” Monster Exhaust for the 2017-2019 Chevy Silverado and GMC Sierra 2500HD & 3500HD Duramax L5P. This DPF-back exhaust system features constant-diameter 5” mandrel bent aluminized steel tubing and a massive patented tip which virtually eliminates backpressure after the DPF and can help prevent trailer meltdown. The Monster Exhaust boasts 85% less backpressure than stock, leading to more power and increased fuel economy. The Monster Exhaust also provides a 15% reduction in exhaust temperature two feet behind the tip during particulate filter regeneration.

Key Features

  • 5 inch constant-diameter DPF-back system
  • 15% reduction in exhaust temperature 2’ behind the tip during regen
  • 85% less backpressure than stock
  • 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 Stock & Aftermarket 5th Wheel Hitches
  • Fits Trucks with Aftermarket Airbags


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.
