Banks Power 48996 Monster Exhaust System 5" DPF-Back for Select 2017-2019 GM 2500HD/3500HD (6.6L)

Fits select 2017-2019 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD (6.6L Duramax L5P).

The Banks Power 48996 Monster Exhaust is a heavy-duty 5-inch DPF-back system engineered to eliminate the restrictive nature of factory piping while managing the extreme heat generated during L5P regeneration cycles. By replacing the narrow 2.85-inch factory nozzle with 5-inch constant-diameter mandrel-bent tubing, this system provides a 192% greater flow area. This results in a massive 85% reduction in backpressure, allowing your Duramax to breathe more efficiently for improved throttle response and longevity.

A critical feature for towing, the included SideKick tip utilizes a 6.5" x 7.5" ob-round design that angles exhaust gases away from the vehicle. This geometry allows ambient air to mix with and diffuse hot exhaust, lowering exit temperatures by 15% to prevent the "trailer meltdown" common with high-temp regen cycles. The 409 stainless steel construction ensures long-term durability, while the polished chrome tip is designed to resist heat-related browning.
