FLOWMASTER MUFFLERS 817344 Features:

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 a mild interior tone, and is suited to customers looking for efficiency improvements without a lot of noise. The system is constructed from 3.00-inch mandrel-bent 409 stainless steel tubing flowing into a 50 Series Big Block™ performance muffler for a moderate exterior tone with a mild to moderate interior tone and maximum power. The system is perfect for towing applications since the tailpipe exits behind the right side rear wheel to avoid blowing exhaust on your boat or trailer when towing. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, this system includes all necessary parts, hardware and easy to follow instructions.
