A 5-inch stainless steel DPF-back exhaust that exits out the side of the truck ahead of the rear wheel instead of out the back, leaving the DPF and DEF/SCR emissions hardware stock.
why this one — Banks quotes 89% less backpressure at the DPF and a 15% lower exhaust temperature during regen for this exact part number, and the side-exit SideKick tip keeps the pipe clear of a bumper-mounted hitch. Honest downsides: it is Single Rear Wheel only, and Banks was showing it backordered when the price was checked.
Banks publishes no quantified hp/tq figure for this SKU. The published claims are 89% less backpressure at the DPF and a 15% exhaust-temperature reduction during regen.
