SYS 04-08 FORD F-150

The Flowmaster® Flow FX Cat-back exhaust system is designed for 2004-2008 Ford F-150 trucks with 4.6L and 5.4L engines. This bolt-on system is manufactured using durable 409 stainless steel throughout, and features a 3.00-inch inlet pipe leading to a single inlet/dual outlet Flow FX® straight-through muffler for a deep, moderately aggressive sound and maximum performance. The dual 2.50-inch mandrel-bent tailpipes are custom routed to clear the factory spare tire and tow hitch without any clearance issues and exit out the sides behind the rear tires, which is ideal when towing so you don't blow exhaust fumes on your boat, vehicle or trailer. The system is then finished off with a pair of large 4.50-inch black ceramic coated stainless steel tips, giving your F-150 an aggressive look to go with the sound of the Flow FX performance muffler. This system utilizes the factory hanger locations and includes detailed instructions and all necessary hardware for an easy at home installation. Notes: Fits all 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.
