"For the person who wants a subtle custom appearance with all the benefits that a Flowmaster® Cat-back exhaust system provides. S.O.S. (Single out side) systems are the perfect choice. Our Force II® systems delivers a moderate exterior tone and mild to moderate interior tone, and are suited to customers looking for efficiency improvements without a lot of noise. This system is constructed from large 3.00-inch mandrel-bent aluminized steel tubing flowing into a 70 Series™ Big Block II™ muffler for a deep mellow tone. The 3.00-inch tailpipe uses the factory hangers for a quick and easy installation and is finished off with a turn down style tip cut into the tubing. This exit location is especially recommended for towing applications since it will not be blowing exhaust on your boat or trailer. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Fits Standard Cab/Long Bed trucks only. Fits Standard Cab/Long Bed trucks only.
