A 5-inch stainless steel exhaust system that replaces everything from the diesel particulate filter (DPF) back, improving flow versus the stock 4-inch system while leaving the DPF, catalyst, and DEF/SCR system completely stock.
why this one — This is the only true 5-inch DPF-back system Banks publishes for the 2024-2026 L5P, and its patented Exhaust Pressure Control Module (U.S. Patent 12618353) is a documented, SKU-specific feature (prevents false power-derate codes) rather than a generic pipe swap.
Banks markets this as a DPF-back exhaust for reduced backpressure and lower regen exhaust temps, not a quantified hp/tq gain - no dyno or claimed number published for this SKU.
