A 5-inch stainless steel DPF-back exhaust with a side-exit SideKick tip for the LML-era Sierra HD, leaving the DPF and DEF/SCR emissions hardware stock.

why this one — One part number covers both the 2011-2014 GMT900 and 2015-2016 K2 Sierra HD bodies, and unlike the newer Banks kits it does fit dually trucks. Honest downsides: it does not fit Single Cab Long Bed at all, Banks lists Sierra 3500 HD coverage only through 2015, and a 2016 Sierra 3500HD needs an extra NOx sensor bung (PN 52255) welded in at your own cost.

why no number is shown

Banks publishes no quantified hp/tq figure for this SKU. The value proposition is backpressure and regen-temperature reduction, not horsepower.
