SYS 04-08 FORD F-150

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 3.00-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. Aluminized Steel exhaust systems are covered by our 3-year Limited Warranty Note: This Force II system is also available in Stainless Steel with a Lifetime Limited Warranty. Check out part# 817403. Fits both 2/4 wheel drive models and all wheelbases.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
