I ordered the Gibson "Super Truck" exhaust system for my stepside Ford replacing a DanaMax system. Through no fault of their own, the system was not shipped from Gibson as promised, but it was shipped within two weeks of the order. The Super Truck system did require a head pipe from the "cats" to the muffler; no problem as I saved the pipe from the previous system (3" stainless) and purchased a sleeve to join the systems together. The torque and horsepower increased...big time. Fuel mileage did increase, if I keep my foot out of it, by about 2mpg. It is not real loud, but others hearing the rumble know the difference. It looks good and sounds great, and boy does it perform...
