Flowmaster American Thunder exhaust systems are designed with the latest exhaust technology available--resulting in improved acceleration, passing power, and fuel mileage. A key to these performance upgrades is Flowmaster's use of mandrel-bent tubing, which allows superior exhaust gas flow. The systems also feature mufflers (single or dual) that deliver plenty of the rich Flowmaster sound you expect. Components are built from stainless steel or aluminized steel; and some models include tips. American Thunder exhausts are available in more than a hundred configurations for fitment on specific truck and car applications.

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.
