For the person who wants a subtle custom appearance with all the benefits that a Flowmaster Cat-back exhaust system provides, the S.O.S. (single out side) systems are the perfect choice. This Force II® system delivers a moderate exterior tone and mild interior tone, and is suited to customers looking for efficiency improvements without a lot of noise. The system is constructed from 3.00 in. mandrel-bent aluminized tubing flowing into a Super 50 Series™ muffler for a moderate exterior tone with a mild to moderate interior tone. This system is especially recommended for towing applications since the tailpipe exits behind the right side rear wheel. 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. Notes: Fits 2/4 wheel drive models with a Standard Cab/Short bed configuration with 119 in. wheelbase.
