A 5-inch stainless steel DPF-back exhaust with a patented obround slash-cut tip, covering all 2017-2019 L5P cab/bed configurations including dually (DRW) models.
why this one — Unlike the 2020-2022/2024-2026 SKUs, this one explicitly covers DCSB/DCLB/CCSB/CCLB configurations AND dually (SRW+DRW) models per Banks own fitment table - the broadest single-SKU coverage found for any year range this session, and compatible with stock/aftermarket fifth wheels and airbags per the same page.
Banks does not publish a quantified hp/tq figure for this SKU - value proposition is backpressure/regen-temperature reduction, not a horsepower claim.
