Overview

For the person who wants a subtle custom appearance with all the benefits that a Flowmaster® Force II® cat-back exhaust system provides, the S.O.S. (Single out side) systems are the perfect choice. The 3.00-inch mandrel-bent aluminized steel tubing flows into a large case dual inlet 50 Series™ Big Block performance muffler that delivers a deep moderate exterior tone while retaining a mild to moderate interior tone. The 3.00-inch tailpipe uses the factory hanger locations for an easy installation and is finished off with a large 3.50-inch polished 304 stainless steel tip. This system is best suited towards customers looking for efficiency improvements without a lot of noise. Especially recommended for towing applications. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts, hardware and is covered by our 3-year Limited Warranty.
