Exhaust System, Swept Side, Particulate Filter-Back, Stainless Steel, Polished Tip, Kit

Gibson diesel swept side exit exhaust systems decrease backpressure, reduce exhaust temperatures, and enable the engine to produce more torque and horsepower. Dyno-tested results have proven increases of as much as 32 hp and 60 lbs.-ft. of torque. They're available with heavy-duty stainless steel or aluminized steel tubing for extended durability. The single cat-back exhausts feature a large 4 in. mandrel-bent tailpipe that maintains constant exhaust flow through the bend for outstanding performance.

The included Superflow muffler offers a straight-through design and is fully welded, baffled, and chambered for better volume efficiency and unrestricted flow; it's not packed or screened, so there's nothing to blow out. These systems also feature a giant 5 in. high-polished stainless steel slash tip, zinc plated 3/8 in.-1/2 in. thick factory-style hangers, zinc plated heavy-duty clamps—and are 50-state emissions legal. They will not affect your factory warranty. The single turbo-back exhaust systems include all of the above, plus a large-diameter downpipe from off the turbo. Order the model and options recommended for your vehicle.
