Requires: Single Rear Wheel (SRW) only. Banks explicitly states this kit does not fit Dual Rear Wheel (dually) trucks.
A 5-inch stainless steel exhaust that replaces everything from the diesel particulate filter (DPF) back, flowing better than the stock 4-inch system while leaving the DPF, catalyst and DEF/SCR emissions hardware completely stock.
why this one — The only 5-inch DPF-back system Banks publishes for the 2024-2026 Sierra HD, and its Exhaust Pressure Control Module is a documented SKU-specific feature that prevents false power-derate codes rather than a generic pipe swap. Honest downside: Banks states it does not fit Dual Rear Wheel trucks, so Sierra 3500HD dually owners are excluded.
Banks publishes no hp/tq figure for this SKU. The claim is reduced backpressure and lower exhaust temperature during regen, not horsepower.
