A 5-inch stainless steel DPF-back exhaust with an obround slash-cut tip, covering every 2017-2019 Sierra HD cab and bed combination including dually trucks.
why this one — This is the only Banks HD exhaust in this lane that covers dually trucks, DCSB/DCLB/CCSB/CCLB plus DRW, so Sierra 3500HD dually owners are not locked out the way they are on the 2020-2022 and 2024-2026 kits, and it works with both stock and aftermarket fifth wheels. Honest downside: the obround tip is a plainer look than the side-exit SideKick used on the newer kits.
Banks publishes no quantified hp/tq figure for this SKU. The value proposition is backpressure and regen-temperature reduction, not horsepower.
