The Flowmaster® FlowFX 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 FlowFX® 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 FlowFX 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.
