For the person who wants the look of a traditional dual exhaust system with all the benefits that a Flowmaster® Cat-back exhaust system provides, our Force II® systems are the perfect choice. This system includes tailpipes for both dual out the rear and dual out the side (recommended for towing applications) so you can choose the one that fits your lifestyle. Force II systems deliver a moderate exterior tone and moderate to mild interior tone, and are suited to customers looking for efficiency improvements without a lot of noise. This system includes a specially designed stainless steel PRO™ series oval case muffler, all mandrel-bent stainless steel tubing and uses the factory hanger locations for an easy hassle free installation you can do at home. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, this system includes all necessary parts and hardware for easy installation.
