The Force II® system is the perfect choice for the person who wants a subtle custom appearance with all the benefits and sound that a Flowmaster® single cat-back exhaust provides. The system delivers a moderate exterior tone and mild to moderate interior tone over the factory exhaust and ideally suited for customers looking for efficiency improvements without a lot of noise. This Force II system is a bolt-on system and bumps the tubing size up to a 3-inch mandrel-bent aluminized steel tubing flowing into the improved muffler design of the Super 50™ Series muffler over the stock exhaust. The mandrel-bent tailpipe uses the factory hanger locations making installation a breeze and is finished off with a 3.50-inch polished stainless steel tip. The Force II system is ideal for daily drivers and especially light towing applications such as boats and RV's. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation you can do at home. All aluminized steel exhaust systems are covered by our 3-year Limited Warranty. Notes: Fits Standard Cab/Long bed with 133-inch wheelbase only.
